Session Goal

The session aimed to analyze and enhance the performance of FAISS-based vectorstore retrieval systems by examining current matching techniques and identifying areas for improvement.

Key Activities

  • Analyzed the effectiveness of vectorstore retrievers using FAISS and embeddings to match queries related to deep learning models like BERT and Wav2Vec 2.0.
  • Evaluated mismatches in retrieval when queries focused on deep learning models but passages centered on statistical inference.
  • Introduced key concepts in experimental design relevant to statistical analysis and data interpretation.
  • Provided critical analysis and recommendations for improving FAISS retrieval setups, focusing on index type selection, query refinement, and embedding model choices.
  • Addressed challenges related to length mismatches in FAISS retrieval and proposed mitigation strategies such as chunking and query expansion.
  • Outlined best practices for developing quote finders and paragraph search engines, emphasizing precision and advanced retrieval techniques.

Achievements

  • Identified specific issues with current FAISS retrieval setups and proposed actionable improvements.
  • Enhanced understanding of experimental design principles and their application in improving retrieval accuracy.

Pending Tasks

  • Implement the recommended improvements in FAISS retrieval setups and evaluate their impact on retrieval accuracy.
  • Further explore the integration of experimental design principles in refining retrieval strategies.
