Latest Patents
One of his latest patents is a search system designed to provide search results using query understanding and semantic binary signatures. This technology enhances the processing of search queries by returning semantically relevant results. The system generates an inventory semantic index that includes binary hashing signatures associated with inventory listings. This index is categorized and partitioned for efficient searching. When a search query is received, relevant categories are identified, and a binary hashing signature is created for the query. The system then calculates Hamming distances to determine semantic relevance.
Another notable patent involves the detection of miscategorizations using an unsupervised statistical language model (SLM) approach combined with structured data. This method trains models using sample item listings and calculates perplexity for item titles. A gradient boosting machine (GBM) is employed to generate a miscategorization classification score, enhancing the accuracy of item listings.
