Recommendation engines use various data analytics techniques to analyze user behavior, including purchase history, browsing patterns, and even demographic information. They can be broadly classified into three types:
- Collaborative Filtering: This approach relies on the behavior and preferences of similar users to make recommendations. For instance, if User A and User B have similar interests, the system might suggest products liked by User A to User B.
- Content-Based Filtering: This method focuses on the attributes of items and user preferences. If a user has shown interest in specific types of products, the engine suggests similar items based on those preferences.
- Hybrid Methods: Combining both collaborative and content-based filtering, hybrid methods offer more accurate recommendations by leveraging the strengths of both approaches.
