Book Recommendation System with Bert

📌 Overview

This repository hosts the quantized version of the bert-base-cased model fine-tuned for movie reccommendation tasks. The model has been trained on the wykonos/movies dataset from Hugging Face. The model is quantized to Float16 (FP16) to optimize inference speed and efficiency while maintaining high performance.

🏗 Model Details

Model Architecture: bert-base-cased
Task: Book Recommendation System
Dataset: Hugging Face's wykonos/movies
Quantization: Float16 (FP16) for optimized inference
Fine-tuning Framework: Hugging Face Transformers

🚀 Usage

Installation

pip install transformers torch

Loading the Model

python

from transformers import BertTokenizerFast, BertForSequenceClassification
import torch

Question Answer Example

python

model_name = "AventIQ-AI/bert-movie-recommendation-system"
model = BertForSequenceClassification.from_pretrained(model_name)
tokenizer = BertTokenizerFast.from_pretrained(model_name)

genre_to_label = {
    "Action": 0, "Adventure": 1, "Animation": 2, "Comedy": 3, "Crime": 4,
    "Documentary": 5, "Drama": 6, "Family": 7, "Fantasy": 8, "History": 9,
    "Horror": 10, "Music": 11, "Mystery": 12, "Romance": 13, "Science Fiction": 14,
    "TV Movie": 15, "Thriller": 16, "War": 17, "Western": 18
}

def recommend_movies(genre, top_n=10):
    """Return a list of movies for a given genre."""
    if genre not in genre_to_label:
        return "Unknown Genre"
    # Filter dataset for movies in the requested genre
    genre_movies = df[df["genres"].str.contains(genre, case=False, na=False)]["title"].tolist()
 
    # Return top N movies (or all if fewer exist)
    return genre_movies[:top_n]

genres_to_test = ["Horror", "Comedy", "Drama"]
for genre in genres_to_test:
    recommended_movies = recommend_movies(genre)
    print(f"Genre: {genre} -> Recommended Movies: {recommended_movies}")

⚡ Quantization Details

Post-training quantization was applied using PyTorch's built-in quantization framework. The model was quantized to Float16 (FP16) to reduce model size and improve inference efficiency while balancing accuracy.

Evaluation Metrics: NDCG

NDCG → If close to 1, the ranking matches expected relevance. Our model's NDCG score is 0.84

🔧 Fine-Tuning Details

Dataset

The wykonos/movies dataset was used for training and evaluation. The dataset consists of texts.

Training Configuration

Number of epochs: 5
Batch size: 8
Evaluation strategy: epochs
