Title: The Innovative Mind of Sankar Basu

Introduction

Sankar Basu is a prominent inventor based in Tenafly, NJ (US). He has made significant contributions to the field of technology, holding a total of 10 patents. His work primarily focuses on enhancing search technologies and audio-visual speech recognition.

Latest Patents

One of his latest patents is titled "Adaptive Probabilistic Query Expansion." This invention involves a method, system, and computer program for adaptively processing a query search. The process includes an expanding operation that transforms the query into sub-queries, with at least one sub-query being expanded probabilistically. A retrieving operation is employed to gather results from the sub-queries, and a merging operation consolidates these results into a comprehensive search outcome. Additionally, an adapting operation is designed to modify the search to increase the relevance of results upon repeated searches. Another notable patent is the "Method and Apparatus for Audio-Visual Speech Detection and Recognition." This invention outlines techniques for speech recognition that involve processing a video signal from an arbitrary content video source and an associated audio signal. The method recognizes portions of the processed audio signal using the processed video signal to generate an output signal that represents the audio.
