Session Goal

The goal of this session was to develop and optimize a retrieval system using FAISS to enhance search capabilities and efficiency.

Key Activities

  • Explored various AI models for text-based tasks, categorizing them into non-generative and generative models.
  • Developed a hierarchical retrieval system integrating BM25 and FAISS for efficient information access.
  • Reflected on the evolution of NLP technologies and the role of transformers and attention mechanisms in modern AI applications.
  • Conducted a deep dive into transformers and CNNs, comparing their applications in NLP and vision tasks.
  • Planned updates to the data science curriculum to align with future industry demands.
  • Implemented embedding summaries for FAISS search and validated the embedding process with Python commands.
  • Developed an incremental FAISS indexing script with chunk ID mapping for efficient data retrieval.
  • Analyzed FAISS retrieval quality, focusing on semantic relevance and ranking consistency.

Achievements

  • Successfully developed a multi-pass retrieval pipeline using FAISS and BM25.
  • Improved the FAISS indexing process with chunk ID mapping and incremental indexing.
  • Enhanced the retrieval quality of FAISS by addressing semantic relevance and ranking consistency.

Pending Tasks

  • Further optimization of FAISS for web scraping to improve query accuracy and result quality.

Outcome

The session resulted in a robust FAISS retrieval system with improved indexing and retrieval quality, setting the foundation for future enhancements in search optimization.
