Product Quantization (PQ) is a compression technique that significantly reduces memory usage for large vector datasets, making it more efficient than storing full-precision vectors. This method involves dividing each vector into smaller chunks and then applying k-means clustering to these chunks. The compressed representation of a vector is then formed by storing the IDs of the closest cluster centroids for each chunk, rather than the full vector data. AI
IMPACT Enables more memory-efficient storage and retrieval of large vector embeddings, crucial for scaling AI applications.
