摘要
Multi-vector retrieval models (e.g., ColBERTv2) offer high retrieval accuracy but suffer from efficiency problems at scale. Recently, several methods have been developed to enhance the efficiency of multi-vector retrieval. On one hand, the state-of-the-art GPU-based method PLAID-GPU exploits the...
