Comparing Token Pruning Approaches for Multi-Vector Retrieval
Ferdinand Schlatt · Hanno Barschel · Matthias Hagen
摘要
The computational costs of the transformer-based multi-vector retrieval model ColBERT depend on the number of vectors used to represent queries and documents. Common strategies to lower the costs thus prune the vectors to a fixed number or relative to the sequence length. We compare standard prun...
