Singular Value Decomposition (Mathematical Overview)



We are talking about SVD and it is the single most important decomposition in linear algebra.

Let us say we have a matrix X which a collection of data column vector x1, x2,..., xm.

There are a couple of examples from where this matrix could come from.

For example:
I could take a bunch of pictures of people's faces.
Let us say we have a picture of a person's face.

We reshape that image into a tall million by 1 column vector.
And so on and so forth till m.

xn lies in Rn 



Another example could that this could a matrix coming from physical system. I have some fluid flow around circle, and we are generating this data with time repeatedly.

Each state is represented in the form of column vector of shape n X 1.



Through SVD:

We take this matrix X and we represent this matrix as a product of three other matrices.

X = (U)(Sigma)(V-Transpose)

The U matrix and V matrix are called Unitary matrices or Orthogonal matrices. 
The matrix Sigma is a diagonal matrix.

On writing it again in Matrix form:

U is an n-by-n matrix.

In matrix Sigma, there will only be 'm' non-zero diagonal values as there are only 'm' rows in matrix X. Everything else is zero.

Last matrix is this V-transpose.
V = [v1, v2, v3,..., vm]



We are taking are data matrix X and represent in the form of U, Sigma, and V.

The columns of U have the same shape as columns of X so if x1 million-by-1 vector then u1 is also a million-by-1 vector.

Column vectors in U are Eigen faces and u1 is more important than u2 and so on, so forth. They give us a basis to represent our original matrix X.

Column vector are heirarchically arranged representing the variance that goes column by colun in the vector X.

U and V are unitary.
That means:
(U-transpose)(U) = (U)(U-transpose) = I (identity matrix) of shape nXn

U is orthogonal that means:
U-transpose == U-inverse 

For V:

(V-transpose)(V) = (V)(V-transpose) = I (identity matrix) of shape mXm

For Sigma:

It is a diagonal matrix.
It is non-negative and heirarchical.

sig1 >= sig2 >= sig3 >= sig4 >= ... >= sigm >= 0

These heirarchichal property leads us to:
u1, sig1 and v1 are more important than u2, sig2 and v2, and so on and so forth.

The relative importance of each column vector is given by the values in the Sigma matrix.

U -> Left Singular Vectors
V -> Right Singular Vectors
X -> Singular Values

Values in X are orderdered by importance.

If some of the Sigma values sig-n are very, very small, then we can ignore them and chop our matrices into dominant columns of U and V.

Now: Eigen Faces.

X was representing a human face.
Since, u1, u2, etc are of same size of vector x1, x2, and so on and so forth. 
That implies: Vectors u1, u2, u3... can be reshaped into Eigen Faces.

Columns of V:
Taking the example of Eigen fluid flow in time:

U would be energy vectors (Eigen flows) u1, u2, u3,...

In V: v1 would essentially be the time series for the first mode u1.
v2: is how much eigen fluid differs in time after t1.
V: Eigen Time Series 

In case of human faces

V-transpose:
[
 [v1-transpose]
 [v2-transpose]
 [v3-transpose]
]

A column in V-transpose:
would tell me of all of those Eigen faces to add them upto x1.
v1-transpose can understood as: mixtures of U's used to make X's

SVD is guaranteed to exist. And, it is unique.

OK Cupid (looking into a free match-making software)

This article was written back in 2016... "This is not good, if somebody has a problem with a post then at least have the courtesy to inform/let know the author about it", that's what I have say to begin with and to the OK Cupid community, escorts community and call girls community.
I am a true admirer of free and open source software, but do not know what to say about this app OK Cupid.
Some people out there tried to benefit the society by giving it a free and good enough dating app but then the app lacks with a system of feedback and reporting, good user authentication system, among many other features. This allows users to use this app in ways not intended by its developers; one has to do more research on it to know if these are bugs or features. Well, now there are people, call girls and escort services who use this OK Cupid app to advertise themselves, as if we are already not seeing enough advertisements in the app's "hot or not" section. Now when I said 'they advertise' they are literally advertising their phone numbers, chat application (like Skype, Kik, WeChat, etc.) IDs to connect via video calling or photo sharing apps later.
The application searches for matches based on the user's location but then it uses some very stupid location management system and it does not even accurately predict your present location. Another bug, or feature I should say, is that even if you are in Delhi, it lets you change your location to well-known places by guesswork like Mumbai or Bengaluru, and then show you the matches from that location.
Oh god, I hope one of the Okc developers read this.
To make everyone's life simple, I have a short list of contact details of those girls from the app, ping me if you need it.

Singular Value Decomposition (SVD) Overview

Singular Value Decomposition (SVD)

It is a data reduction tool.
Let's say you have big data with a lot of dimensions then SVD can be used to reduce the dimensions into key features.

SVD is the first step in most dimension reduction techniques.

It is a data driven generalization of Fourier Transform (FFT).
FFT is one of the most useful transformation in most of the mathematics based on sine and cosine expansions to approximate functions. There is also Bessel's function, Aries' functions and Spherical harmonics.

And this was the technique of last generation of computation science.

SVD is used to map a system of interest in a system that is system.

But in many systems of interest today. Like turbulent flow over the Boeing wing.
There is not an easy tranformation function available to help in this complex problem.

SVD is going to allow us to do tailor the coordinate system based on the problem that we have.

What SVD can do for you?

1. Solve Ax = B (linear system of equations) for non-square A matrices.
We are going to use it particularly for Linear Regression models.

This has been useful in detection of disease medical science usecase.

2. It is also the basis of PCA (Principal Composition Analysis).

3. SVD helps in building and understanding correlation matrices.

It is used by Google in PageRank algorithm.
It is the basis of many facial recognition algorithms of Facebook.
It is also used in the recommendation systems of Amazon and Netflix.

Reasons for using it:

1.
It is based on simple and interpretable linear algebra. Anytime you have a data matrix you can apply SVD to it.

2.
It is scalable.

Hammer, Chisel and Grinder (Journal 2022-May-06)

Index of Journals

"9 years later and the sounds of chisel and hammer, and grinder affect me."

I had lied down around 12 AM but still I have not been able to catch sleep at 01:50 AM.
Tejbhan Vidhayak mason completed his work today.
I don't seem to have any headache but just some kind of little irritation and anxiety in head.
One of the reasons that I am not able to sleep is because I might have slept for roughly 5 hours in the afternoon.
In the evening, I was winding up the paperwork for electrician (Dinesh Saini), painter (Md. Nizamuddin), mason (Tejbhan Vidhayak) and plumbing work (Vijay Mittal and Md. Aslam).
Something funny happened today:
I mistakenly did not join the "HR Disciplinary Discussion" for complaints against me of unavailability around 4:30 and she had to reschedule it at 6 PM.
Before going to bed, I was working on finding my psychiatrist prescriptions to send them to HR so that she is aware of everything she should know.
That was how I spent my day.

Took medication for sleep, anxiety and depression.
Now am going sleep with Moti next to me in my bed.

Thank you for reading.

Bagging in overcoming variance of a classifier, clustering algorithm or regressor

Bootstrap aggregating

Bootstrap aggregating, also called bagging, is a machine learning ensemble meta-algorithm designed to improve the stability and accuracy of machine learning algorithms used in statistical classification and regression. It also reduces variance and helps to avoid overfitting. Although it is usually applied to decision tree methods, it can be used with any type of method. Bagging is a special case of the model averaging approach. 

Bagging: Sampling with replacement

Build classifier on each bootstrap sample
Each sample has probability (1 - (1 - 1/n) ^ n) of being selected in training set.

Sampling data for bagging



Probability that a sample will be selected in m rounds of bagging



Probability that ensemble will make an error with majority voting decision making technique

The Concept of Lift in Association Rules Mining

Let's look at a problem first:


    
        
             
        

        
            Coffee
        

        
            Not Coffee
        
        
             
        
    

    
        
            Tea
        

        
            150
        

        
            50
        

        
            200
        
    

    
        
            Not Tea
        

        
            650
        

        
            150
        

        
            800
        
    

    
        
             
        

        
            800
        

        
            200
        

        
            1000
        
    


Tea -> Coffee
What is the support and confidence of the above rule?

Support = #(tea and coffee) / #(total)

Confidence : P (Coffee | Tea)
= #(tea and coffee) / #(tea)

Support for the rule is 15% while the confidence is 75%.

Lift = Confidence(A -> B) / Support(B)
= Confidence of the rule / Support of the consequent

If you look in general:
The percentage of people drinking coffee is 80%.

But when we apply the rule: Tea -> Coffee
Confidence: Percentage of people drinking coffee who are also drinking tea is:
150 / 200 = 75%

So, ( Tea -> Coffee ) shows they are negatively correlated.
This is the importance of lift.

Formula 1: Lift = P (A and B) / ( P(A) * P(B) )

Formula 2: Lift = Ratio between the rule's confidence and support of the rule consequent = c(A -> B) / s(B)

Definition

Life is a measure of the performance of an association rule at predicting or classifying cases as having an enhanced reponse (with respect to the population as a whole), measured against a random choice targeting model. A targeting model is doing a good job if the response within the target is much better than the average for the population as a whole.
