This was a class project I made for CS4964 Computational Geometry. It walks through the theory and code behind 4 popular clustering algorithms.

SOP For Performig BLR in Python

SOP For Performig BLR in Python

A standard operating procedure for performing Bayesian linear regresssion, in python, from scratch.

Functional Analysis Backing of Quantum Mechanics

Functional Analysis Backing of Quantum Mechanics

These are my typed notes on the mathematics of quantum mechanics. These follow the lectures by Frederic Schuller.

Varational Fluid Mechanics

Varational Fluid Mechanics

Some ramblings of mine while trying to study the principle of least action in terms of fluid mechanics.

A Gaussian Process Classifier Made From Scratch, in PyTorch

A Gaussian Process Classifier Made From Scratch, in PyTorch

This explains how to create a GP Classifier with all the theory and code in PyTorch

The Use Of DFT in Catalyst Development

The Use Of DFT in Catalyst Development

A paper for a course I did in catalyst development and characterization. The class was wholy untheoretical and utterly useless for any computational development. I scratched the itch by making this.
