To guard against spurious results from testing a class against a particular CAV, we propose the following simple statistical significance test. Instead of training a CAV once, against a single batch of random examples N, we perform multiple training runs, typically 500. A meaningful concept should lead to TCAV scores that behave consistently across training runs.

This is just the beginning of your journey with deep learning for natural language processing. Keep practicing and developing your skills.


You can retype this code into the console anytime you want to re-roll your dice. However, this is an awkward way to work with the code. It would be easier to use your code if you wrapped it into its own function, which is exactly what we’ll do now. We’re going to write a function named roll that you can use to roll your virtual dice.

It should also be possible to work backwards from the protocol implementations to get us into an even simpler bootstrapping environment. For the time being, we’ll continue wrapping existing CL functionality though.


The code that you place inside your function is known as the body of the function. When you run a function in R, R will execute all of the code in the body and then return the result of the last line of code. If the last line of code doesn’t return a value, neither will your function, so you want to ensure that your final line of code returns a value. One way to check this is to think about what would happen if you ran the body of code line by line in the command line. Would R display a result after the last line, or would it not?

C++ iterate through vectgor

If you are looking to implement your own CNN for text classification, using the results of this paper as a starting point would be an excellent idea. A few results that stand out are that max-pooling always beat average pooling, that the ideal filter sizes are important but task-dependent, and that regularization doesn’t seem to make a big different in the NLP tasks that were considered. A caveat of this research is that all the datasets were quite similar in terms of their document length, so the same guidelines may not apply to data that looks considerably different.


How to Add Statistical Significance to a Table Using the Formattable R Package

A vector is a sequence of elements that share the same data type. These elements are known as components of a vector.

A binary Windows package is not currently provided, though it should follow in the coming months. Advanced users can compile the package by satisfying the dependencies mentioned above for a general Linux installation.


Our experiments suggest TCAV can be a useful technique in an analyst’s toolbox. We provided evidence that CAVs do indeed correspond to their intended concepts. We then showed how they may be used to give insight into the predictions made by various classification models, from standard image classification networks to a specialized medical application.

Some R commands may take a long time to run. You can cancel a command once it has begun by typing ctrl + c. Note that it may also take R a long time to cancel the command.


In this way, the data frame is like a matrix in which each column can represent a different vector type

There are a lot of “learning” debris throughout the code base that are not on the critical path for bootstrapping (or no longer are). These need to be pruned and moved elsewhere so that a consistent, clear path of required code is attentuated.

A key property of vectors in R is that

Don’t forget to save the output of function to an R object. This object will become your new function.


In MULTIPLY blending mode, two colors are multiplied together. Sincethey are between 0 and 1, we expect a darker result unless one of themis 1. How are we going to do this if we have our numbers between 0 and255? Very simple if we use our imagination and consider them fixedpoint numbers!

Now that you know how to use R, let’s use it to make a virtual die. The: operator from a couple of pages ago gives you a nice way to create a group of numbers from one to six.


You can see above there are four strong rules. For example, take ${I2}=>I3$ having confidence equal to 75% tells that 75% of people who bought I2 also bought I3.

You might be thinking that integers can't really have a high dynamicrange. Well it depends: if you know the number's range, say it'sbetween xˆ74 and xˆ77, then you can simply use thisinformation without needing exponents (use shifting). On the otherhand, if this "range" varies here, consider floating point. Note thatif you know the range of your variables, and they have different"ranges", it's possible to use integers to represent the same thing(think of the integer being the mantissa, since the exponent is knownat this code implementation, you don't need to store it). For example,given our variable being between xˆ74 and xˆ77, you onlyneed 77-74=3 extra bits to account for this range, without anyexponent at all. You can then use shifts and other operators to makeit work for other "known" ranges. This is, obviously,"special-purpose", unlike the more "general-purpose" of thefloats.


It's only to get you started, fixed point hides many tricks, just see for yourself

This package was first publicly released in August 2021 and is updated for recent versions of the R language. The package enables use of optimised implementations of homomorphic encryption schemes from the user friendly interactive high-level language R and offers completely transparent use of multi-core CPU architectures during computations. If you are familiar with homomorphic encryption skip to the details below, otherwise read on for a brief introduction.

Lift: Lift gives the correlation between A and B in the rule A=>B. Correlation shows how one item-set A effects the item-set B.


Figure 8: Saliency map results with approximated ground truth: Models trained on datasets with different noise parameter p (rows) and different saliency map methods (columns) are presented. The approximated ground truth is that the network is paying a lot more attention to the image than the caption in all cases, which is not clear from saliency maps.

Graph-based techniques visualize association rules using vertices and edges where vertices are labeled with item names, and item sets or rules are represented as a second set of vertices. Items are connected with item-sets/rules using directed arrows. Arrows pointing from items to rule vertices indicate LHS items and an arrow from a rule to an item indicates the RHS. The size and color of vertices often represent interest measures.


You can run tests with a specified procedure name. The procedure name is different from the test element name because it does not include any class or package name or information about parameterization. In a class-based test, the procedure name is the name of the test method. In a function-based test, it is the name of the local function that contains the test. In a script-based test, it is a name generated from the test section title. For example, if a test element name for a test with parameterization is MyTestClass/myTestMethod(param1=val1,parm2=valB) the procedure name is myTestMethod.

So when you read a vector, and eval it, you actually have to apply those evaluation semantics to build up the resulting vector. In CL, eval just passes the vector through.


There are several built-in functions library and add-on tools available for R and they continue to grow at an incredible rate. Yet programs need performing a task for which no functions exist.

A linear regression in R can be performed using either lme4 package or the plyr package or the nlme approach. For a data set which has multiple vectors, a mixed linear model will be a better approach.


This assumes you already have R itself installed. See here for details if you have not done this yet.

MATLAB has improved the performance of property (dig this) set methods. For more information on these methods, see Property (read full article) Set Methods.


The mex function uses the large-array-handling API (-largeArrayDims option) by default. Best practice is to update your MEX source code to use this library and rebuild the MEX file. For instructions, see Upgrade MEX Files to Use 64-Bit API.

Of course it has certain advantages overfixed point, but that doesn't mean it's for "real" numbers, nor isfixed point. They are both just representations and formats in 1s and0s.


A common representation that people use in RGB colors besides the24-bit one is with floating point scalars. In this case you have Red,Green and Blue stored in 32-bit float each, up to a total of 96 bitsper pixel. The numbers themselves are between 0 and 1. If youunderstood fixed point then you would most probably see how many bytesare wasted here, per color! In my opinion, this floating point stuffis really silly. Even if you want better precision than 24-bit RGB,use 48-bit RGB or 72-bit RGB. The 72-bit one has the same precision asthe floating point one, yet it is smaller (this is because floatswaste 1 byte per color with the exponent and sign, because they areuseless in this situation).

How to Format Areas of a Table Using the Formattable R Package

Multi-layer feed forward networks of Artificial Neural Networks are comparable to Support Vector Machines. The clear benefit for these models over SVM is the fact that these are parametric models with fixed node size, while SVM's are non-parametric. Any artificial Neural Network is made up of multiple hidden layers with variable number of nodes and bias parameters depending upon number of features. On the other hand, an SVM is consisted of a set of support vectors with assigned weights calculated from training set.


How to use vector vector int

In each task, the worker first saw four images along with their corresponding saliency masks. They then rated how important they thought the image was to the model (10-point scale), how important the caption was to the model (10-point scale), and how confident they were in their answers (5-point scale). In total, turkers rated 60 unique images (120 unique saliency maps).

Mining stopped (maxlen reached). Only patterns up to a length of 10 returned!


Another important property of a vector (why not find out more) is its length. This is the number of elements in the vector and can be checked with the function length().

Given is a set of transaction data. You can see transactions numbered 1 to 5. Each transaction shows items bought in that transaction. You can see that Diaper is bought with Beer in three transactions. Similarly, Bread is bought with milk in three transactions making them both frequent item sets.


It can tell you what items do customers frequently buy together by generating a set of rules called Association Rules. In simple words, it gives you output as rules in form if this then that.

Only plotting the best 1000 rules using measure lift (change parameter max if needed)To reduce overplotting, jitter is added! Use jitter = 0 to prevent jitter.


The index vector can even be out-of-order. Here is a vector slice with the order of first and second members reversed.

Note: Support and Confidence measure how interesting the rule is. It is set by the minimum support and minimum confidence thresholds. These thresholds set by client help to compare the rule strength according to your own or client's will. The closer to threshold the more the rule is of use to the client.


Now that we have a notion of distance in our embedding space, we can talk about words that are "close" to each other in the embedding space. For now, let's use Euclidean distances to look at how close various words are to the word "cat".

Is there an R function for finding the index of an element in a vector

Did some experimenting and switched to the earlier loop-focused with-recur macro. Did some more testing and experimentation, and switch over to inlining arity bodies for multiple-arity function definitions. So named functions work, recur works, loop (without destructuring) is implemented (over loop*).


RStudio comes with a tool that can help you build functions. To use it, highlight the lines of code in your R script that you want to turn into a function. Then click Code > Extract Function in the menu bar. RStudio will ask you for a function name to use and then wrap you code in a function call. It will scan the code for undefined variables and use these as arguments.

With the above info in mind, let's look at two examples. Again, weassume both operands are in 8/8 format for simplicity. The firstexample completely truncates the fractional part, hence the resultwill be an integer.

Figure 9: For the cab class, the ground truth was that the image concept was more important than the caption concept. However, when looking at saliency maps, humans perceived the caption concept as being more important (model with 0% noise), or did not discern a difference (model with 100% noise). In contrast, TCAV results correctly show that the image concept was more important. Overall, the percent of correct answers rated as very confident was similar to that of incorrect answers, indicating that saliency maps may be misleading.

One pitfall with the TCAV technique is the potential for learning a meaningless CAV. After all, using a randomly chosen set of images will still produce a CAV. A test based on such a random concept is unlikely to be meaningful.


Note that in practice T and Q vectors are encrypted using secret key K and matrix m

For dev purposes, it’s meaningless though since we’re bootstrapping pretty simply. I don’t plan to hack a custom slime mode to enable documenting multiple- arity functions just for the boostrap.

When you type a command at the prompt and hit Enter, your computer executes the command and shows you the results. Then RStudio displays a fresh prompt for your next command.


As you can see, you start by creating Candidate List for the 1-itemset that will include all the items, which are present in the transaction data, individually. Considering retail transaction data from real-world, you can see how expensive this candidate generation is. Here APRIORI plays its role and helps reduce the number of the Candidate list, and useful rules are generated at the end. In the following steps, you will see how we reach the end of Frequent Itemset generation, that is the first step of Association rule mining.

This worked great and fixed a major problem, where lexical literals were effectively just uneval’d and quoted directly. Now, at eval time, we get custom literals working as in Clojure.


The DiagnosticResult property was a cell arrays of character vectors

Now, you can specify a character encoding of your choice by using the 'Encoding' parameter. Previously, the writetable function used the system’s default encoding when writing to a file and that was the only available option. For example, to set file encoding to support Japanese characters, set the Encoding parameter to Shift_JIS.

Matrices are Data frames which contain lists of homogeneous data in a tabular format. We can perform arithmetic operations on some elements of the matrix or the whole matrix itself in R.


You could complete one lesson per day (recommended) or complete all of the lessons in one day (hardcore). It really depends on the time you have available and your level of enthusiasm.

Of course these "formats" are just imaginary – truth be toldnothing stops you to limit yourself to these "rules". How I actuallyunderstood these things was by looking and analyzing the numbers. Themath behind this is obvious (shifting left is just a form ofmultiplying by powers of 2, but much faster). Let's see, if we havea number with "A" fractional bits, then the value "1" will be encodedas 1<<A. So, when we multiply a number x by this "fixed point" number,we need to arrive at the same base number x. However, multiplyingx with 1<<A will shift x left by A bits. What will we do so our x willremain unchanged? I'll leave it to you as an exercise. Don't belimited to these rules or the formats – and try to think inbinary. I see a lot of people getting confused by fixed point becausethey think in decimal.


Introduction to R Data Types

R will replace an object with its contents whenever the object’s name appears in a command. So, for example, you can do all sorts of math with the die. Math isn’t so helpful for rolling dice, but manipulating sets of numbers will be your stock and trade as a data scientist.

News on Data Science in R Programming

Each time you call dice, R will show you the result of that one time you called sample and saved the output to dice. R won’t rerun sample(die, 2, replace = TRUE) to create a new roll of the dice.


The first step is to convince ourselves that the learned CAVs are aligned with the intended concepts of interest. We first sort the images of any class with respect to CAVs for inspection. Then we learn patterns that maximally activate each CAV using an activation maximization technique for further visual confirmation.

We then train 4 networks, each on a dataset with a different noise parameter p in [0,1]. Each network may learn to pay attention to either images or captions (or both) in the classification task. To obtain an approximated ground truth for which concept each network paid attention, we can test the network’sperformance on images without captions. If the network used the image concept for classification, the performance should remain high. If not, the network performance will suffer. We create image CAVs using each class’s images, and caption CAVs using captions with other pixels in the image randomly shuffled.


The index vector allows duplicate values. Hence, the following retrieves a member twice in one operation.

Classes for Data Science in R Programming

There are two aspects of this computation worth paying attention to: Location Invariance and Compositionality. Let’s say you want to classify whether or not there’s an elephant in an image. Because you are sliding your filters over the whole image you don’t really care where the elephant occurs. In practice, pooling also gives you invariance to translation, rotation and scaling, but more on that later. The second key aspect is (local) compositionality. Each filter composes a local patch of lower-level features into higher-level representation. That’s why CNNs are so powerful in Computer Vision. It makes intuitive sense that you build edges from pixels, shapes from edges, and more complex objects from shapes.


Deep Learning for NLP

Evaluates a CNN architecture on various classification datasets, mostly comprised of Sentiment Analysis and Topic Categorization tasks. The CNN architecture achieves very good performance across datasets, and new state-of-the-art on a few.

R Frequently Asked Questions

However, depending on your implementation, fixed point can have a muchgreater precision, but less accuracy for greater dynamic ranges(notice the difference between precision and accuracy). Since I don'twork with very big or very small numbers (where floats can just "shiftthe number" to the left/right with the help of the exponent, eventhough this yields a very high loss of precision in the number,computations are still done correctly on 24 bits unless you want tocast it into an integer), I prefer fixed point for most of myprograms. Too bad there isn't a fixed point capability in hardware;probably because it can be "emulated" much faster than floating point,and it is not as "general-purpose" as float.


If you build MEX files without using the mex command options -largeArrayDims or -compatibleArrayDims, then review the table in Compatibility Considerations to avoid depending on default behavior that changes in R2017a. For information about the consequences of using the -compatibleArrayDims option to build MEX files, see What If I Do Not Upgrade?

The GIMP manual has a few other examples. To understand more about how convolutions work I also recommend checking out Chris Olah’s post on the topic.

Common Lisp already has a sequence library, but I think Clojure’s is more general and can be trivially extended to new types. Common Lisp’s irrational locking down of SEQUENCE is a hurdle here. The HYPERSPEC will never be updated in my lifetime :) So generic functions are the current way to bridge this stuff.


Above you have seen the example of only 5 transactions, but in real-world transaction data for retail can exceed up to GB s and TBs of data for which an optimized algorithm is needed to prune out Item-sets that will not help in later steps. For this APRIORI Algorithm is used.

Use formattable's align argument to left or right align, the color_bar argument to create colored bars from a given column's values, and the style argument to set font color. In this example we are aligning the first column to the left and the others to the right. We are also adding a color bar to the Average column and changing the color of the Improvement column cells to red or green based on whether the values are greater than 0.


MATLAB provides the following string data type functionality when using Python® features. For more information about string data types, see Characters and Strings.

Sparse Matrix: A sparse matrix or sparse array is a matrix in which most of the elements are zero. By contrast, if most of the elements are nonzero, then the matrix is considered dense. The number of zero-valued elements divided by the total number of elements is called the sparsity of the matrix (which is equal to 1 minus the density of the matrix).


To ensure continued support for building your MEX-files, consider upgrading to another supported compiler. For an up-to-date list of supported compilers, see the Supported and Compatible Compilers website.

That’s followed by a convolutional layer with multiple filters, then a max-pooling layer, and finally a softmax classifier. The paper also experiments with two different channels in the form of static and dynamic word embeddings, where one channel is adjusted during training and the other isn’t.


Vector inside a vector

Graph plots are a great way to visualize rules but tend to become congested as the number of rules increases. So it is better to visualize less number of rules with graph-based visualizations.

It is represented in Itemset Lattice which is a graphical representation of the APRIORI algorithm principle. It consists of k-item-set node and relation of subsets of that k-item-set.


Furthermore, good tricks like multiplying by a power of 2 stillapply. Let's see with the rules (note however that these "rules" areabstract, they do not exist actually, it's just to get you started)– we have a fixed point number of the format (let's say) 8/8,again. Now we want to multiply it by 4. When we shift it left, wemultiply it with an integer: 4. This integer has 0 bits for thefractional part, thus the result will have the same number offractional bits as the number we are multiplying by 4.

This did not carry over into expressions with lexically bound forms that were also data literals. Results kept returning wierd quoted forms for values rather than the actual evaluated forms.

For example, aneurysms (HMA) had a relatively high TCAV score, even though they are diagnostic of a higher DR level (see HMA distribution in Figure 10). However, consistent with this finding, the model often over-predicted level 1 (mild) as level 2 (moderate). Given this, the doctor said she would like to tell the model to de-emphasize the importance of HMA for level 1. Hence, TCAV may be useful for helping experts interpret and fix model errors when they disagree with model predictions.

You’ll notice that a appears next to your result. R is just letting you know that this line begins with the first value in your result. Some commands return more than one value, and their results may fill up multiple lines. For example, the command 100:130 returns 31 values; it creates a sequence of integers from 100 to 130. Notice that new bracketed numbers appear at the start of the second and third lines of output. These numbers just mean that the second line begins with the 14th value in the result, and the third line begins with the 25th value.

When I explained convolutions above I neglected a little detail of how we apply the filter. Applying a 3×3 filter at the center of the matrix works fine, but what about the edges?

Now we gotta think logically – if we, for example, have twonumbers x and y in 8/8 format, then multiplying them will yielda 16/16 result. So, if we want a 8/8 result, we need to shift it right8 bits. For the integer part, just ignore the upper bits, or do thesame as if it overflowed (since you had a 16/16 format and now youwant 8/8).

R vector is the basic data structure, which plays an essential role in R programming. So, let’s start with our tutorial.


How to push vector in 2D vector

As another fun time, I also ran into problems with CLOS and multiple dispatch that were a little unsavory. Had to learn about call-next-method.


If you’re not sure which names to use with a function, you can look up the function’s arguments with args. To do this, place the name of the function in the parentheses behind args.

C++ prin vectori of vecotrs

Cryptographic methods have been used since the dawn of civilisation in order to keep information secret. Fundamentally, an encryption algorithm is a mathematical transformation of your data in such a way as to make it difficult to recover the original information without knowledge of some secret, commonly called a private key.


C++ sort vector of objects by property

In R, Vector is a basic data structure in R that contains element of similar type. These data types in R can be logical, integer, double, character, complex or raw.

Post your code in the comments below. I would love to see what book you choose and how you chose to tokenize it.


The first step in our method is to define a concept of interest. We do this simply by choosing a set of examples that represent this concept or find an independent data set with the concept labeled. The key benefit of this strategy is that itdoes not restrict model interpretationsto explanations usingonly pre-existing features, labels, or training data of the model under inspection.

Match only returns the first encounter of a match, as you requested. It returns the position in the second argument of the values in the first argument.


Provides an implementation of clojure’s lazy sequence abstraction. Implemented in CLOS, and porting the seq protocols. Provides a subset of the clojure core sequence library for CL used in bootstrapping and metaprogramming. The intent is not to have a full port, but a minimally useful subset. Integrates the seq abstraction with CLOS sequence types.

For example, this code plots a line and adds a legend. Then the code plots a second line. The legend automatically updates to include the second line.


Every function in R has three basic parts: a name, a body of code, and a set of arguments. To make your own function, you need to replicate these parts and store them in an R object, which you can do with the function function.

Throughout the book, I’ll put exercises in boxes, like the one just mentioned. I’ll follow each exercise with a model answer, like the one that follows.


R Arithmetic operations with Example

In simple terms, back-propagation learning for Neural networks is gradient descent method. In this method, random weights are initialized to the nodes of the neural network.

You have learned APRIORI, one of the most frequently used algorithms in data mining. You have learned all about Association Rule Mining, its applications, and its applications in retailing called as Market Basket Analysis. You are also now capable of implementing Market Basket Analysis in R and presenting your association rules with some great plots!


P<α/m with m=2) to control the false discovery rate further. All results shown in this paper are CAVs that passed this testing.

In vision, our filters slide over local patches of an image, but in NLP we typically use filters that slide over full rows of the matrix (words). Thus, the “width” of our filters is usually the same as the width of the input matrix. The height, or region size, may vary, but sliding windows over 2-5 words at a time is typical. Putting all the above together, a Convolutional Neural Network for NLP may look like this (take a few minutes and try understand this picture and how the dimensions are computed.


In our example, 1<<8 means 256. Nextmultiply this by the fractional value you wish to find out (0/5 in ourcase), and voila. Note though that if the result yields a fractionalpart, it means the respective value cannot be encoded in those numberof bits, hence we have a "precision loss". Try increasing the numberof fractional bits and see if it reduces the loss. For such"approximated" results I suggest you round it up as it's the bestsolution. Don't be scared of rounding because such small precisionloss won't be too bad.

As above, the encoder must be trained on source documents and then can be used to encode training data, test data and any other data in the future. The API also has the benefit of performing basic tokenization prior to encoding the words.


Recover-literals serves as an auxillary function used in the macro-defining-macro defmacro/literal-walker, which will quietly bind the args for the macro definition to a lexical binding where the args (inputs) are bound to their recover-literals results. This basically ensures that, when using defmacro/literal-walker, we always have access to data literals. Simultaneously, our literals now also work seamlessly in eval with custom evaluation semantics, including in lexical bindings.

It is replaced by the DiagnosticResults property that contains DiagnosticResult objects. The DiagnosticResult property was a cell arrays of character vectors.

R FAQ missing values. Frequently Asked Questions about missing values

This article explains fixed point arithmetic, how it differs fromfloating point and some "general-purpose" operations to get youstarted. It is by no means a comprehensive guide – fixed point hasvery many tricks and I cannot simply explain them all in onearticle. I do show three examples, however.


Pooling also reduces the output dimensionality but (hopefully) keeps the most salient information. You can think of each filter as detecting a specific feature, such as detecting if the sentence contains a negation like “not amazing” for example. If this phrase occurs somewhere in the sentence, the result of applying the filter to that region will yield a large value, but a small value in other regions. By performing the max operation you are keeping information about whether or not the feature appeared in the sentence, but you are losing information about where exactly it appeared. But isn’t this information about locality really useful? Yes, it is and it’s a bit similar to what a bag of n-grams model is doing. You are losing global information about locality (where in a sentence something happens), but you are keeping local information captured by your filters, like “not amazing” being very different from “amazing not”.

Let's analyze the number (without therules). When we divide a number x by 1 we need to arrive at thesame number x. Of course, 1 is expressed as 1<<8 (or 256) iny because it has 8 bits for the fractional part. This means thatwhen we divide a number x with a fixed point number y with thevalue 1, we will arrive at the same number x, but shifted right by8!


Adversarial examples (Szegedy et al, 2021) are small, often visually imperceptible changes to an image which can cause an arbitrarily change to a network’s predicted class. We conduct a simple experiment to see whether TCAV is fooled by adversarial examples. In Figure 11, TCAV returns a high score for the striped concept for zebra pictures.

Histcounts accepts input data of type datetime and duration. Also, you can bin the data using units of time as the bin edges, such as 'second', 'hour', or 'week'.


Consider a random string input with recurring characters. The objective of this task is to count the consecutive patterns and print them along with the character of the repetitive strings. This can be done in R using the dplyr library.

A list can be converted to a vector so that the elements of the vector can be used for further manipulation. All the arithmetic operations on vectors can be applied after the list is converted into vector. To do this conversion, we can use the unlist() function. It takes the list as input and produces a vector.


Data Science in R Programming short tutorials

Imagine that the matrix on the left represents an black and white image. Each entry corresponds to one pixel, 0 for black and 1 for white (typically it’s between 0 and 255 for grayscale images). The sliding window is called a kernel, filter, or feature detector. Here we use a 3×3 filter, multiply its values element-wise with the original matrix, then sum them up. To get the full convolution we do this for each element by sliding the filter over the whole matrix.

I almost gave up, then remembered vaunted warnings from Java land about idiots using Exceptions for control flow. This built on the idea that I could just throw an error if I detected a reduced value, and handle the reduction gracefully outside of the built-in cl:reduce.


If you find out some faster solutions than what I present here, pleaselet me know and I'll add them. Also please remember that the"operators" I present here are just "general-purpose", so don't takethem as the final touch, as they're not even optimal for specificdesign. It's only to get you started, fixed point hides many tricks,just see for yourself. Testing and analyzing is the key to successhere (also a bit of math might help).

Your client gives you data for all transactions that consists of items bought in the store by several customers over a period of time and asks you to use that data to help boost their business. Your client will use your findings to not only change/update/add items in inventory but also use them to change the layout of the physical store or rather an online store. To find results that will help your client, you will use Market Basket Analysis (MBA) which uses Association Rule Mining on the given transaction data.
