A new paper published on arXiv introduces the concept of Multi-Vector (MV) embeddings as a more expressive paradigm for neural information retrieval compared to Single Vector (SV) embeddings. The research formally proves that MV embeddings, which represent data with multiple vectors and use Chamfer similarity, offer a significant advantage over SV embeddings that rely on inner product similarity. The findings establish a strong separation in representation size, confirming the long-held belief within the Information Retrieval community that MV embeddings can capture similarities not approximately representable by SV embeddings.
