AI startup Vectara has launched a new technology called Boomerang, which enhances AI accuracy through vector embeddings. Boomerang is a neural information retrieval model that generates a new method for vector embeddings that allows cross-lingual retrieval. Vectara aims to reduce the risk of AI hallucinations and provide more accurate and interpretable results. The complexity of Boomerang's vector embedding approach will be elaborated in future research papers.
