# **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. 📈
## **Demo 🎥**
https://github.com/user-attachments/assets/c13063e2-c943-4b51-b664-545248d37f06
## **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.
