Retrieval with Learned Similarities
Retrieval plays a fundamental role in recommendation systems, search, and natural language processing (NLP) by efficiently finding relevant items from a large corpus given a query. Dot products have b...

🧵(3/4) MoL achieves dense retrieval-level speed on GPUs, while delivering 20-30% better Hit Rate@50-400 on 100M+ item DBs (arxiv.org/abs/2306.04039, arxiv.org/abs/2407.13218). These gains make a compelling case for migrating web-scale vector databases to Retrieval with Learned Similarities (RAILS).

🧵(2/4) Our paper introduces Mixture-of-Logits (MoL) - a universal approximator of similarity functions unifying sparse/dense retrieval, multi-embeddings, and generative approaches. Beyond theory, MoL achieves SotA from sequential retrieval on Transformers/HSTU to finetuning LMs for RAG/QA.

Issue is, we've already had a historic opportunity to make social media fully user-controlled and unbiased, yet our lawmakers chose to optimize for tech oligarchs' net worth instead...
