Hacking the Bivariate Gaussian Distribution

Leave a Comment / Artifact, Code, Computational Biology, Conceptual, Implementation, Tutorial / By Sajil C. K.

In one of our earlier posts, we have seen how we can visually relate the parts of the one-dimensional Gaussian distribution equation. In this post, we will follow the same strategy to understand the terms that comes up with a Multivariable Gaussian distribution. We will focus on the Bivariate Gaussian distribution as distributions of higher-order …

Visualizing MinMax Scaling

Leave a Comment / Artifact, Conceptual, Implementation, Tutorial / By Sajil C. K.

This article explains the minmax scaling operation using visual examples. Normalization of vectors, an array of values, signals is often used as a preprocessing step before many algorithms. For example, in machine learning, some types of algorithms are prone to different inherent scales of features. In such situations normalization is done to give the same …

Coding a Simple Markov Decision Process

Leave a Comment / Artifact, Code, Computational Biology, Conceptual, Implementation, Tutorial / By Sajil C. K.

A Markov Decision Process (MDP) is a mathematical framework used to model decision-making situations where the outcome of a decision depends on both the current state of the system and the actions taken by the decision maker. In an MDP, the decision maker is represented as an agent, and the system is represented as a …
