Patent number: 10832162Abstract: Techniques for model based data processing are proposed. In one example, a computer-implemented method is as follows. A first model is determined from a first category of data processing models and a second model is determined from a second category of data processing models. The second category can be different from the first category in some instances. Performance of a first combined model of the first and second models can be compared with performance of the first model. A target model for processing data can be selected from the first combined model and the first model based on the comparing.Type: GrantFiled: September 8, 2016Date of Patent: November 10, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Boliang Chen, Stephen Mingyu Chu, Jing Chang Huang, Dong Sheng Li, Junchi Yan, Weipeng Zhang

Patent number: 10333715Abstract: Techniques are provided for providing a local computation service on client device authorized by a remote service provider while keeping local data private from the remote service provider. In one example, a computer-implemented method comprises transmitting, by a device operatively coupled to a processor, a homomorphic encryption public key and homomorphically encrypted input data to a service provider. The computer-implemented method also comprises receiving, by the device from the service provider, a homomorphically encrypted signature generated based on the homomorphic encryption public key, the homomorphically encrypted input data, and a homomorphic encryption equivalent defined function.Type: GrantFiled: November 14, 2016Date of Patent: June 25, 2019Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Stephen Mingyu Chu, Tobias Enders, Dong Sheng Li, Pankaj Srivastava, Junichi Yan, Tomomi Yoshioka

Patent number: 8121840Abstract: A system and method for speech recognition includes determining active Gaussians related to a first feature stream and a second feature stream by labeling at least one of the first and second streams, and determining active Gaussians co-occurring in the first stream and the second stream based upon joint probability. A number of Gaussians computed is reduced based upon Gaussians already computed for the first stream and a number of Gaussians co-occurring in the second stream. Speech is decoded based on the Gaussians computed for the first and second streams.Type: GrantFiled: June 2, 2008Date of Patent: February 21, 2012Assignee: Nuance Communications, Inc.Inventors: Stephen Mingyu Chu, Vaibhava Goel, Etienne Marcheret, Gerasimos Potamianos

Patent number: 6633845Abstract: The invention provides a method and apparatus for automatically generating a summary or key phrase for a song. The song, or a portion thereof, is digitized and converted into a sequence of feature vectors, such mel-frequency cepstral coefficients (MFCCs). The feature vectors are then processed in order decipher the song's structure. Those sections that correspond to different structural elements are then marked with corresponding labels. Once the song is labeled, various heuristics are applied to select a key phrase corresponding to the song's summary. For example, the system may identify the label that appears most frequently within the song, and then select the longest duration of that label as the summary.Type: GrantFiled: April 7, 2000Date of Patent: October 14, 2003Assignee: Hewlett-Packard Development Company, L.P.Inventors: Beth Teresa Logan, Stephen Mingyu Chu
