LeetPath: A Graph-Based LeetCode Question Recommender 🧭🔍

LeetPath is a personalized question recommendation system designed for LeetCode users. Using graph-based structures, topic modeling, and Markov Random Field, the system analyzes user interaction, question similarity, and topic relevance to suggest the most appropriate questions for continued skill improvement. 📈

Features 🌟

• 🔍 Personalized Recommendations: Suggests questions based on user activity and skills.
• 🧠 Topic Modeling: Groups questions by related topics for better understanding.
• 📊 Interactive Dashboard: Displays user stats and recommended questions.
• ⚡ Real-Time Performance: Fast and efficient recommendations using graph-based algorithms and belief propagation.

Tech Stack 🛠️

• Frontend: Next.js with Tailwind CSS for a responsive and interactive UI.
• Backend: Flask for API endpoints for the model and Go for fetching user data.
• Database: MongoDB for storing user data.
• Authentication: Firebase for secure user login and management.
• GraphQL: For efficient and flexible data querying.

Deployment and Hosting 💻

• The recommendation engine is deployed on Google Cloud Platform using App Engine.
• The backend code is deployed on OnRender.
• The frontend is hosted on Vercel.

How It Works 📊

• Question Similarity: Content-based filtering using TF-IDF and cosine similarity to recommend questions based on their content similarity.
• Topic Modeling: Grouping questions by latent topics using a custom topic modeling algorithm (similar to Latent Dirichlet Allocation).
• Markov Random Field (MRF): Models relationships between questions, accounting for user engagement, difficulty, and question similarities.
• Belief Propagation: Used to refine potential values in the MRF and improve recommendation accuracy.
