In summertime when I go out, I don’t take the raincoat with me. On what basis am I not expecting it to rain during summer?. Isn’t it my past experience gives me that knowledge and estimate the outcome?. The expected value in probability theory leverages such a pattern in data to make a good representation …
Throughout my academics when I come across the term tensor, my brain send reflex that “something complicated, take a break, relax and read later”. Often, I gave a thought, Am I reading it Tensor or Terror!! Physicists use Tensors to describe properties of systems which vary with direction called anisotropic systems whereas for mathematicians Tensors …
I am sure you might have heard the term bootstrapping already. The first time I heard it, I felt it like jargon. Later I came to know that there are four different scenarios the term comes in. All of them have some basic roots but are in different subject domains. The boot-strapping We all know …

LaTeX Installation Instructions Windows In Windows, you need to install two programs called MiKTeX and TeXstudio. Please be careful to install …
What is a vector? I know you might be already thinking- “a vector is something which has magnitude and direction”. But that’s old school definition. I also used to think that way, but after I left the academic world, I had to dig deeper. The more I explored, the deeper the concept became. This post …
Introduction In this tutorial, I am going to code up the iterative policy improvement algorithm. It starts from a uniform random policy, computes the value function, and use it to update the policy again. This process continuous until the optimal policy is reached. The policy evaluation part was covered on a previous tutorial. This tutorial …
Introduction Bandit problems are the simplest possible reinforcement learning scenario. Here the bandit machine can have k arms and pulling each arm leaves the user a reward. One of the arms will be giving higher rewards in the long run and moreover this pattern could be changing over a time period. Think of the scenario …
Did you ever needed to do automated PDF creation using a table of information?. Creating a Word document with certain formatting, styles, and tables would be the easy choice for a few pages of data. But what if you have data that might fill 100+ pages?. Would you do it by hand? or can we …

Here in this article, I am trying to explain the process of creating inset pictures within Python plots. In many cases of data visualization, we need to make the best use of available space for plots. In my experience, each plot is unique in its own way so that few improvements here and there makes …
Hello World, Before discussing about matrix multiplication, let me start this discussion with even more basic question. What does simple multiplication means? To me, it feel like this. Say your IQ is 120. You have a magic wand, you wave it and say “Let my IQ go twice”. With multiplication you can grow or shrink …
