🎬 Movie Recommender System 📽️

Overview

This project is a movie recommender system built using Streamlit. It lets users search for their favorite movies or get a "Surprise Me" suggestion. The app fetches live movie details—like posters, trailers, ratings, cast, and more—using the TMDB API. It also displays trending movies and tracks your recently viewed films. Simply put, it helps you discover movies that match your taste through an easy-to-use, interactive interface.

Learning Journey 🗺️

I built this project out of a love for movies and a desire to dive into machine learning in a practical way. Here’s a glimpse into my journey:

• Inspiration:
  I’ve always been passionate about movies, and I wanted to create something that not only recommends films but also tells a story through data. Merging my interests in cinema and technology felt like the perfect creative outlet.

• Why I Made It:
  I set out to design a system that could give personalized movie suggestions by leveraging real-time data and machine learning. I also wanted to experiment with deep learning using the MNIST dataset to sharpen my skills and explore new techniques.

• Challenges Faced:

  • API Key Integration: One major challenge was choosing the right API for movie data. I had a better IMDb option available, but due to licensing and cost constraints, I opted to use TMDB. Integrating TMDB’s API and managing its rate limits pushed me to learn more about API integration and error handling.
  • Balancing Complexity & Usability: I had to find the right balance between a robust, feature-rich system and a clean, user-friendly interface.
  • Model Tuning: Fine-tuning the deep learning model to achieve high accuracy involved a lot of trial and error, pushing me to learn more about early stopping and data augmentation techniques.

• What I Learned:

  • API Integration: Seamlessly connecting with external APIs (like TMDB) to fetch live movie data.
  • Web Development: Building an interactive and user-friendly interface with Streamlit.
  • Deep Learning: Hands-on experience in constructing, training, and optimizing a CNN with TensorFlow and Keras.
  • Data Handling: Mastering data preprocessing and visualization to simplify complex concepts.

• The Value It Adds:
  This project isn’t just a technical exercise—it’s a story of blending creativity with technology. It deepened my understanding of real-world problem-solving through machine learning and continues to inspire me to explore, learn, and share knowledge.

Every step of this journey has enriched my skills and reinforced my belief that learning is best when it’s fun, creative, and shared.

3. Install Required Packages:

   pip install -r requirements.txt

4. Set Up Your TMDB API Key:

   • Create a .streamlit/secrets.toml file.
   • Add your TMDB API key:

     [tmdb]
     api_key = "your_api_key_here"

   • Alternatively, set your TMDB API key as an environment variable.

5. Run the Application:

   streamlit run app.py

Usage🚀

Running the Streamlit App

Start the movie recommender system with:

streamlit run app.py

Features include:

• Movie Search: Select a movie from the dropdown to view details and recommendations.
• Surprise Me: Let the system randomly choose a movie for you.
• Trending Movies: See a curated list of current trending movies.
• Recently Viewed: A sidebar tracks your recent movie views for quick access.

Running the Jupyter Notebook

Explore the deep learning experiment:

1. Launch Jupyter Notebook:

   jupyter notebook "Movie Recommender System.ipynb"

2. Execute the cells to follow along with the model building, training, evaluation, and visualization processes.

Dataset📊

The project utilizes the TMDb 5000 Movie Dataset, which includes:

1. tmdb_5000_movies.csv:

   • 5000 movies with detailed metadata.
   • Features: title, overview, genres, keywords, cast, crew.
   • Release dates spanning multiple decades.
   • Budget and revenue information.

2. tmdb_5000_credits.csv:

   • Comprehensive cast and crew information.
   • Details about directors, producers, and writers.
   • Character names and actor mappings.

Key Statistics:

• Total Movies: 5,000
• Unique Genres: 20
