Poseidon Linux is an Ubuntu variant for scientists. It is developed and maintained by a group of young scientists from Brazil and Germany. Poseidon comes pre-installed with many software related to GIS, Mapping, CAd, 2D/3D modelling, statistics, genetics etc that are frequently used by Professors, students and scientists. The inclusion of many academics related software and the ease of use have made it a popular Linux distribution among academicians, who usually prefer to stay away from Linux.2. Vinux
Vinux is an Ubuntu-based Linux distribution for visually impaired people. It is developed by Tony Sales who teaches at National College for the Blind in Hereford, United Kingdom. Tony was frustrated with the default accessibility support provided by mainstream Linux distributions and this is when decided to develop a Linux distribution solely for blinds and partially sighted users.
Vinux provides a screen-reader, full-screen magnification and support for Braille displays out of the box. It can be used alongside Windows or as the sole operating system. It has been developed in such a way that a visually impaired person can install it on his/her own without much effort. A great OS, I would say.3. Mathbuntu

Singular Value Decomposition (SVD) is a common dimensionality reduction technique in data science
We will discuss 5 must-know applications of SVD here and understand their role in data science
We will also see three different ways of implementing SVD in PythonIntroduction
“Another day has passed, and I still haven’t used y = mx + b.“
Sounds familiar? I often hear my school and college acquaintances complain that the algebra equations they spent so much time on are essentially useless in the real world.
Well – I can assure you that’s simply not true. Especially if you want to carve out a career in data science.
Linear algebra bridges the gap between theory and practical implementation of concepts. A healthy understanding of linear algebra opens doors to machine learning algorithms we thought were impossible to understand. And one such use of linear algebra is in Singular Value Decomposition (SVD) for dimensionality reduction.
You must have come across SVD a lot in data science. It’s everywhere, especially when we’re dealing with dimensionality reduction. But what is it? How does it work? And what are SVD’s applications?
I briefly mentioned SVD and its applications in my article on the Applications of Linear Algebra in Data Science. In fact, SVD is the foundation of Recommendation Systems that are at the heart of huge companies like Google, YouTube, Amazon, Facebook and many more.
We will look at five super useful applications of SVD in this article. But we won’t stop there – we will explore how we can use SVD in Python in three different ways as well.
And if you’re looking for a one-stop-shop to learn all machine learning concepts, we have put together one of the most comprehensive courses available anywhere. Make sure you check it out (and yes, SVD is in there as part of the dimensionality reduction module).Table of Contents

Why is SVD used in Dimensionality Reduction?
3 Ways to Perform SVD in PythonApplications of Singular Value Decomposition (SVD)
We are going to follow a top-down approach here and discuss the applications first. I have explained the math behind SVD after the applications for those interested in how it works underneath.
You just need to know four things to understand the applications:
SVD is the decomposition of a matrix A into 3 matrices – U, S, and V
S is the diagonal matrix of singular values. Think of singular values as the importance values of different features in the matrix
The rank of a matrix is a measure of the unique information stored in a matrix. Higher the rank, more the information
Eigenvectors of a matrix are directions of maximum spread or variance of data
In most of the applications, the basic principle of Dimensionality Reduction is used. You want to reduce a high-rank matrix to a low-rank matrix while preserving important information.SVD for Image Compression
It minimizes the size of an image in bytes to an acceptable level of quality. This means that you are able to store more images in the same disk space as compared to before.
Here’s how you can code this in Python:
If you ask me, even the last image (with n_components = 100) is quite impressive. I would not have guessed that it was compressed if I did not have the other images for comparison.SVD for Image Recovery
We’ll understand image recovery through the concept of matrix completion (and a cool Netflix example).
Matrix Completion is the process of filling in the missing entries in a partially observed matrix. The Netflix problem is a common example of this.
The basic fact that helps to solve this problem is that most users have a pattern in the movies they watch and in the ratings they give to these movies. So, the ratings-matrix has little unique information. This means that a low-rank matrix would be able to provide a good enough approximation for the matrix.
This is what we achieve with the help of SVD.
Where else do you see this property? Yes, in matrices of images! Since an image is contiguous, the values of most pixels depend on the pixels around them. So a low-rank matrix can be a good approximation of these images.
Here is a snapshot of the results:
Chen, Zihan. “Singular Value Decomposition and its Applications in Image Processing.” ACM, 2023SVD for Eigenfaces
The original paper Eigenfaces for Recognition came out in 1991. Before this, most of the approaches for facial recognition dealt with identifying individual features such as the eyes or the nose and developing a face model by the position, size, and relationships among these features.
The Eigenface approach sought to extract the relevant information in a face image, encode it as efficiently as possible, and compare one face encoding with a database of models encoded similarly.
The encoding is obtained by expressing each face as a linear combination of the selected eigenfaces in the new face space.
Let me break the approach down into five steps:
Collect a training set of faces as the training set
Find the most important features by finding the directions of maximum variance – the eigenvectors or the eigenfaces
Choose top M eigenfaces corresponding to the highest eigenvalues. These eigenfaces now define a new face space
Project all the data in this face space
For a new face, project it into the new face space, find the closest face(s) in the space, and classify the face as a known or an unknown face
You can find these eigenfaces using both PCA and SVD. Here is the first of several eigenfaces I obtained after performing SVD on the Labelled Faces in the Wild dataset:
As we can see, only the images in the first few rows look like actual faces. Others look noisy and hence I discarded them. I preserved a total of 120 eigenfaces and transformed the data into the new face space. Then I used the k-nearest neighbors classifier to predict the names based on the faces.
You can see the classification report below. Clearly, there is scope for improvement. You can try adjusting the number of eigenfaces to preserve and experiment with different classifiers:
Have a look at some of the predictions and their true labels:
You can find my attempt at Facial Recognition using Eigenfaces here.SVD for Spectral Clustering
Clustering is the task of grouping similar objects together. It is an unsupervised machine learning technique. For most of us, clustering is synonymous with K-Means Clustering – a simple but powerful algorithm. However, it is not always the most accurate.
Consider the below case:
Clearly, there are 2 clusters in concentric circles. But KMeans with n_clusters = 2 gives the following clusters:
K-Means is definitely not the appropriate algorithm to use here. Spectral clustering is a technique that combats this. It has roots in Graph theory. These are the basic steps:
Start with the Affinity matrix (A) or the Adjacency matrix of the data. This represents how similar one object is to another. In a graph, this would represent if an edge existed between the points or not
Find the Laplacian (L) of the Affinity Matrix: L = A – D
Find the highest k eigenvectors of the Laplacian Matrix depending on their eigenvalues
Run k-means on these eigenvectors to cluster the objects into k classes
You can read about the complete algorithm and its math here. The implementation of Spectral Clustering in scikit-learn is similar to KMeans:
View the code on Gist.
You will obtain the below perfectly clustered data from the above code:SVD for Removing Background from Videos
I have always been curious how all those TV commercials and programs manage to get a cool background behind the actors. While this can be done manually, why put in that much manual effort when you have machine learning?
Think of how you would distinguish the background of a video from its foreground. The background of a video is essentially static – it does not see a lot of movement. All the movement is seen in the foreground. This is the property that we exploit to separate the background from the foreground.
Here are the steps we can follow for implementing this approach:
Create matrix M from video – This is done by sampling image snapshots from the video at regular intervals, flattening these image matrices to arrays, and storing them as the columns of matrix M
We get the following plot for matrix M:
What do you think these horizontal and wavy lines represent? Take a moment to think about this.
The horizontal lines represent the pixel values that do not change throughout the video. So essentially, these represent the background in the video. The wavy lines show movement and represent the foreground.
We can, therefore, think of M as being the sum of two matrices – one representing the background and other the foreground
The background matrix does not see a variation in pixels and is thus redundant i.e. it does not have a lot of unique information. So, it is a low-rank matrix
So, a low-rank approximation of M is the background matrix. We use SVD in this step
We can obtain the foreground matrix by simply subtracting the background matrix from the matrix M
Here is a frame of the video after removing the background:
Pretty impressive, right?
We have discussed five very useful applications of SVD so far. But how does the math behind SVD actually work? And how useful is it for us as data scientists? Let’s understand these points in the next section.What is Singular Value Decomposition (SVD)?
I have used the term rank a lot in this article. In fact, through all the literature on SVD and its applications, you will encounter the term “rank of a matrix” very frequently. So let us start by understanding what this is.Rank of a Matrix
The rank of a matrix is the maximum number of linearly independent row (or column) vectors in the matrix. A vector r is said to be linearly independent of vectors r1 and r2 if it cannot be expressed as a linear combination of r1 and r2.
Consider the three matrices below:
In matrix A, row r2 is a multiple of r1, r2 = 2 r1, so it has only one independent row. Rank(A) = 1
In matrix B, row r3 is a sum of r1 and r2, r3 = r1 + r2, but r1 and r2 are independent. Rank(B) = 2
In matrix C, all 3 rows are independent of each other. Rank(C) = 3
The rank of a matrix can be thought of as a representative of the amount of unique information represented by the matrix. Higher the rank, higher the information.Singular Value Decomposition (SVD)
So where does SVD fit into the overall picture? SVD deals with decomposing a matrix into a product of 3 matrices as shown:
If the dimensions of A are m x n:
U is an m x m matrix of Left Singular Vectors
S is an m x n rectangular diagonal matrix of Singular Values arranged in decreasing order
V is an n x n matrix of Right Singular VectorsWhy is SVD used in Dimensionality Reduction?
You might be wondering why we should go through with this seemingly painstaking decomposition. The reason can be understood by an alternate representation of the decomposition. See the figure below:
The decomposition allows us to express our original matrix as a linear combination of low-rank matrices.
In a practical application, you will observe that only the first few, say k, singular values are large. The rest of the singular values approach zero. As a result, terms except the first few can be ignored without losing much of the information. See how the matrices are truncated in the figure below:
Using SVD, we are able to represent our large matrix A by 3 smaller matrices U, S and V
This is helpful in large computations
We can obtain a k-rank approximation of A. To do this, select the first k singular values and truncate the 3 matrices accordingly3 Ways to Perform SVD in Python
We know what SVD is, how it works, and where it is used in the real world. But how can we implement SVD on our own?
The concept of SVD sounds complex enough. You might be wondering how to find the 3 matrices U, S, and V. It is a long process if we were to calculate these by hand.
Fortunately, we do not need to perform these calculations manually. We can implement SVD in Python in three simple ways.SVD in NumPy
NumPy is the fundamental package for Scientific Computing in Python. It has useful Linear Algebra capabilities along with other applications.
You can obtain the complete matrices U, S, and V using SVD in numpy.linalg. Note that S is a diagonal matrix which means that most of its entries are zeros. This is called a sparse matrix. To save space, S is returned as a 1D array of singular values instead of the complete 2D matrix.
View the code on Gist.Truncated SVD in scikit-learn
In most common applications, we do not want to find the complete matrices U, S and V. We saw this in dimensionality reduction and Latent Semantic Analysis, remember?
We are ultimately going to trim our matrices, so why find the complete matrices in the first place?
In such cases, it is better to use TruncatedSVD from sklearn.decomposition. You specify the number of features you want in the output as the n_components parameter. n_components should be strictly less than the number of features in the input matrix:
View the code on Gist.Randomized SVD in scikit-learn
Randomized SVD gives the same results as Truncated SVD and has a faster computation time. While Truncated SVD uses an exact solver ARPACK, Randomized SVD uses approximation techniques.
View the code on Gist.End Notes
I really feel Singular Value Decomposition is underrated. It is an important fundamental concept of Linear Algebra and its applications are so cool! Trust me, what we saw is just a fraction of SVD’s numerous uses.
I encourage you to check out this Comprehensive Guide to build Recommendation Engine from scratch to realize the power of SVD for yourself. Building this project will surely add value to your resume (and enhance your own skillset!).
Ah, the Internet cafe; home to yuppies, flavored lattes, and The Pirate Bay? If you haven’t heard, Swedish Internet cafe operator, Global Gaming Factory X, today bought The Pirate Bay for $7.8 million. The new owner says it intends to sail The Pirate Bay out of its murky waters, and put the former rogues gallery on the straight and narrow. In other words, The Pirate Bay is going legitimate.
“Following the completion of the acquisitions, GGF intends to launch new business models that allow compensation to the content providers and copyright owners.”
If reading that news just upset you, then perhaps you are one of the millions of one-eyed curs who regularly pillage copyrighted content with the help of the site. But before you draw your sword in anger over the death of your beloved pirate haven, perhaps this is your shining moment to choose a life free from lurking in the seedier regions of the Internet. Pirates can reform themselves after all, and maybe it’s not too late for you to avoid the fate that led Jammie Thomas to the RIAA’s gallows.
So before you do something hasty — like moving over to torrent tracker alternative site Mininova — prop up your wooden leg and read my list of five things The (New) Pirate Bay needs to avoid to keep its six million registered users happy.
1) Don’t turn into Napster
Graphic: Diego AguirreIn its heyday, Napster was the ultimate file-sharing site. But its rogue life was cut short when heavyweight lawyers from the record industry caught up with Napster. Now, Napster is a shell of its former self, and has been re-launched at least three times with as many new strategies. Currently, Napster users can download five songs a month and get unlimited streaming for a monthly subscription fee of five dollars. Is it restrictive? Yes. Do people like it? Not as much as the first incarnation of Napster. The Pirate Bay needs to avoid Napster’s fate at all costs.
Illustration: Lou BeachPeople came to The Pirate Bay for everything from MP3s to episodes of their favorite TV shows. Would TPB’s user base be willing to pay? Maybe, but legitimacy means content deals; while that may be a good thing for some, content deals also mean restrictions on what can be viewed, shared and downloaded. If there’s one thing a TPB user hates, it’s to be held up by business deals and red tape. There are plenty of other torrent sites out there, and TPB’s reformation is not going to stop people from getting their hands on the most current episodes of popular shows like Weeds, Dexter, Californication and The Office. Not to mention rogue copies of movies and music.
Graphic: Diego AguirreSay what you want about the Swedish outlaws, but the creators of TPB knew how to run a popular Website. Sure, it took on some water every now and then, but most of the time the site was up and running. TPB has been out of its creator’s hands for only a few hours, and the site has already dropped off the digital horizon. At the time of this writing, chúng tôi was returning a network timeout. Has TPB gone to Davy Jones’ locker already?
The Pirate Bay was primarily a conduit for file sharers to find each other, so the site really had no control over download speeds. That being said, today’s torrent technology could stand to go a little faster. TPB’s new owner has promised to speed things up for users, and has acquired Peerialism, a p2p technology specialty firm, to aid its task.
