Latest Patents

Xingwei He holds a patent titled "Dense retrieval employing progressive distillation training." This patent describes technologies that enhance the dense retrieval and ranking of search results. The process begins with receiving a query that indicates a computing context or user input. An embedding of the query is computed using a first encoder, and candidate results are selected from a pool of potential results based on the query's embedding and the embeddings of the potential results. A similarity score for the first candidate result is computed using a second encoder, which is trained based on an order metric that defines a ranking over a training set of potential results. The first encoder is trained based on the output of the second encoder prior to computing the embedding of the query. The candidate results are then ranked based on the similarity score of the first candidate result, and results responsive to the query are identified based on this ranking. Finally, the identified results are output to a computing device.
