REINFORCE-based Contradiction Correction in LLMs

Built a BERT-based contradiction detection model fine-tuned with LoRA and improved by a REINFORCE RL framework, achieving ~90% detection accuracy and reducing contradiction rate from 65% to 44%.

Dialogue Summarizer

Fine-tuned PEGASUS LLM on SAMSUM corpus and deployed a FastAPI- and Docker-based summarization app with AWS and CI/CD integration, streamlining workflows and automated testing.

AI Powered Hotel Recommendation System

Enhanced natural language understanding in GPT-4o by fine-tuning retrieval mechanisms using agents and RAGs to reduce hallucinations, delivering real-time, preference-aligned hotel recommendations with higher precision.

Drugs, Side Effects, and Medical Conditions Analysis

This project involves analyzing a pharmaceutical dataset to explore the relationships between drugs, side effects, and medical conditions using data visualization, association mining, and various other techniques.

Human Artery Vein Classification with U-Nets

A U-Net based deep learning model built to classify and differentiate between human artery and vein images for medical diagnostics and research.

Bot Clean

A simple bot designed to navigate through a matrix and clean all of its dirty cells.

QnA Bot

A TF-IDF based parser to parse through paragraphs and answer questions.

Color-based Classification

A Computer Vision Program to detect the color of the balls and get the timestamps of each ball entering and exiting the quadrants.

PHP-based Student Management Portal

A PHP-based student portal that helps students manage their academic and extracurricular activities, featuring modules for login, timetable, lost and found, assignments organizer, password change, and internship updates.

CS50 AI Mini-Projects Repository

A collection of 12 unique AI programs developed using various AI concepts, including Optimization, Machine Learning, and NLP.

Social Distancing Monitor

An image processing project that utilizes an inbuilt Histogram of Oriented Gradients (HOG) descriptor to recognize people in a given area and estimate the distance between them
