What is it about?
LibVQ is a powerful toolkit that tailors and integrates various techniques into a user-friendly framework for VQ-based neural retrieval. It collaborates seamlessly with a user-provided well-trained retriever and optimizes vector quantization based on user-configured settings. The optimized VQ parameters are then off-loaded to the ANN index back-end (e.g., FAISS) to enhance the end-to-end retrieval quality significantly. This makes LibVQ a crucial "junction" that bridges the gap between embedding learning and ANN index in the current landscape of neural retrieval development.
