Thinking FastWith LLMs:Enabling Personalized Product Discovery & Recommendations

Step-by-Step Tutorial: Building a Recommendation Engine with LLMs

Introduction:

In this tutorial, we will learn how to build a recommendation engine using LLMs (Large Language Models) for enabling personalized product discovery and recommendations.

Step 1: Understanding the Motivation

• LLMs help in extracting important facets of a product from its description.
• The goal is to recommend products that are similar to the one a user is viewing.

Step 2: Data Ingestion and Processing

• Ingest product data with descriptions and corresponding facets.
• Use a prompt template to instruct the model on extracting specific facets from the product descriptions.
• Ensure data quality by handling exceptions and unknown values in the prompts.

Step 3: Embedding and Similarity Search

• Utilize a vector database for storing text embeddings and metadata.
• Perform similarity searches to find products similar to the one being viewed by the user.
• Use embeddings to search for similar products based on specific facets.

Step 4: Implementing a Retrieval System

• Enable users to filter products based on specific attributes like RAM size or storage capacity.
• Use embeddings and metadata to facilitate efficient retrieval of products matching user preferences.

Step 5: Enhancing Data Quality and User Experience

• Leverage prompts to streamline the process of adding new features or facets to the recommendation system.
• Empower subject matter experts or business users to create new prompts without developer intervention.
• Continuously improve the system by incorporating user feedback and refining the recommendation process.

Step 6: Feedback and Iteration

• Encourage audience feedback on the level of detail and complexity in the tutorial.
• Gather insights on which areas need further clarification or deeper exploration.
• Use feedback to enhance future tutorials and address specific audience preferences.

Conclusion:

By following these steps, you can effectively build a recommendation engine using LLMs to enable personalized product discovery and enhance user engagement. Remember to iterate on the process based on feedback and continuously improve the recommendation system for optimal results.

This tutorial provides a comprehensive guide on leveraging LLMs for building a recommendation engine and enhancing the user experience in product discovery and recommendations.
