Math is about packing things down into small conceptual boxes that we can upload into our brains. It's not about thousand page books... Don't settle for a partial understanding.

Consistent way of ensuring i.i.d. condition for infinitely many random variables

In probability theory, the term i.i.d. condition is loosely stated to describe random variables that are independent of each other and are identically distributed. This is equivalent to saying that there is a joint distribution whose marginals are identical and independent of each other. In an infinite dimensional setting, Daniel-Kolmogorov theorem is invoked to explore the conditions under which such a joint distribution can be established.

Starting point of linear regression and why we prefer matrix algebra

Ironically, in many cases, especially in linear regression, calculations become simpler when approached through multi-dimensional matrix algebra rather than one-dimensional methods. Let's explore the foundational concepts of linear regression to understand this phenomenon.

Getting started Pintos project with MacOS + some tips

The Pintos project is a mini-implementation of an operating system. If you're finding it challenging to install a source file and simulate it on macOS, here is a guideline to help you with the process. Additionally, I'll offer some tips to ease the initiation into the project.

System-level routines for the UNIX operating system and their applications

We discuss here some system-level implementations of functions in C.

Convergence of Hard Thresholding Algorithm

We present a greedy-based approximation algorithm designed to reconstruct the vector xx. It is applicable to matrices AA that satisfy the condition δ3s112\delta_{3s}\leq\frac 1{12}. Additionally, the article includes a proof demonstrating the convergence of this algorithm.

Approximation of Gaussian Kernel

We explain the motivation of the Kernel method in machine learning theory and how one might go about overcoming the computational challenges.

Mathematical Preprint Trend Analysis

I analyzed the trend of Mathematical Preprint for the last 15 years.

Obsidian linear modeling

I built upon a final project from an advanced linear modeling course, diving deeper into the statistical nuances of obsidian sample data.
