Latest Patents

Sumeet's latest patents include innovative technologies that address complex challenges in search queries. One of his patents focuses on "Index searching with non-Euclidean representations." This invention allows items within an index to be converted from classic geometry and embedded into a hyperbolic space. The hyperboloids in this hyperbolic space enable higher precision classifications of items relative to their hierarchical structure. Additionally, a received search query can be transformed into hyperbolic space and mapped as a query hyperboloid against an answer space containing hyperboloids for items within the index. This method allows for the determination of distances or overlaps between hyperboloids to generate a set of search results.

Another significant patent is "Reformulation of tail queries for product searches." This technology provides a method for reformulating a tail query into a head query with the same purchase intent by mapping the tail query to the head query. The invention includes learning a reasonable embedding on historical head queries, which can be refined using rewards generated from a persistently noisy oracle. This approach compensates for the lack of historical behavioral signals for tail queries. Furthermore, a contextual sampling technique utilizing text-based or oracle-based rewards can be implemented to mitigate biases introduced by persistent noise in the oracle. Numerical experiments on large-scale e-commerce datasets demonstrate that these technologies can outperform several conventional approaches to query reformulation.
