In layman terms Story – 1 Imagine you just moved into a new neighborhood, and you […]

Building a Practical Retrieval-Augmented Personal Assistant (RAG)

The elements of information discussed here are all present in my github repository. with Ollama, LangChain, and Chroma 1. Why I Built This Large Language Models are powerful, but they hallucinate and forget your private knowledge. We set out to build a small, local Retrieval-Augmented Generation (RAG) assistant that: 2. What Is RAG (In Plain […]

Data Mining Essentials

Whether you’re preparing for a quiz or just brushing up on fundamentals, this guide distills the key concepts from Data Mining into bite-sized, memorable chunks. Let’s dive in! Understanding Machine Learning Tasks Regression vs. Classification: Know Your Output The fundamental distinction in supervised learning comes down to what you’re predicting: Pro tip: If someone asks […]

Building a Minimal LangChain + Ollama Demo

This post walks through a tiny, practical example that uses LangChain primitives and a local Ollama server to run a prompt-based summarization. The project is intentionally small so you can learn the core ideas quickly: extracting prompts, initializing an LLM client, composing a chain, and running it locally. Repository used in this post: llangchain-tutorial What you’ll […]
