Personalized product recommendations using collaborative filtering
This e-commerce recommendation system utilizes collaborative filtering techniques to suggest products based on user preferences and behavior patterns. By analyzing historical transaction data, the system identifies similarities between users and products to generate personalized recommendations.
The system processes a dataset of e-commerce transactions to build a user-item interaction matrix. Using this matrix, it applies collaborative filtering algorithms to predict user preferences for products they haven't purchased yet.
The recommendation engine was built using Python and Pandas for data manipulation, with the following key components:
Metric | Value | Status |
---|---|---|
Mean Absolute Error | 0.42 | High |
Root Mean Square Error | 0.58 | High |
Top-10 Precision | 0.85 | High |
Recall@20 | 0.76 | Medium |
