Trustees of Boston University Assigned Patent
Storage and retrieval system using online supervised hashing
By Francis Pelletier | May 11, 2021 at 2:30 pmTrustees of Boston University, Boston, MA, has been assigned a patent (10,990,626) developed by Sclaroff, Stanley, Boston, MA, Cakir, Fatih, Allston, MA, and He, Kun, Providence, RI, for a “data storage and retrieval system using online supervised hashing.“
The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A data storage and retrieval system employs online supervised hashing for indexing a data set and retrieving data items therefrom. A hash-based mapping is used to generate hash codes for indexing content items. Data items may be retrieved based on either/both a query label (using corresponding codewords) and the content item itself (using the hash codes). The hash-based mapping is updated using an objective function of distance between the hash codes and respective codewords for labels of labelled content items, preserving semantic similarities of content items. The codewords may be error-correcting codes. Techniques for efficiently updating the index include (1) cycle-based updating and ternary codewords, and (2) reservoir sample-based method of determining when to trigger an update.”
The patent application was filed on September 23, 2016 (Appl. No.15/754,904).
