Patent number: 8554560Abstract: Discrimination between two classes comprises receiving a set of frames including an input signal and determining at least two different feature vectors for each of the frames. Discrimination between two classes further comprises classifying the two different feature vectors using sets of preclassifiers trained for at least two classes of events and from that classification, and determining values for at least one weighting factor. Discrimination between two classes still further comprises calculating a combined feature vector for each of the received frames by applying the weighting factor to the feature vectors and classifying the combined feature vector for each of the frames by using a set of classifiers trained for at least two classes of events.Type: GrantFiled: September 4, 2012Date of Patent: October 8, 2013Assignee: International Business Machines CorporationInventor: Zica Valsan

Patent number: 8311813Abstract: Discrimination between at least two classes of events in an input signal is carried out in the following way. A set of frames containing an input signal is received, and at least two different feature vectors are determined for each of said frames. Said at least two different feature vectors are classified using respective sets of preclassifiers trained for said at least two classes of events. Values for at least one weighting factor are determined based on outputs of said preclassifiers for each of said frames. A combined feature vector is calculated for each of said frames by applying said at least one weighting factor to said at least two different feature vectors. Said combined feature vector is classified using a set of classifiers trained for said at least two classes of events.Type: GrantFiled: October 26, 2007Date of Patent: November 13, 2012Assignee: International Business Machines CorporationInventor: Zica Valsan

Patent number: 7970762Abstract: A user profile and/or the suggestions computed based thereon are obtained taking a special set of user features into account. The user features are defined to represent a typical general behaviour of an individual user in respect to the application where the user profile is used. In other words, for each application where a user profile is used a special set of user features are defined which are able to represent a typical general behaviour of an individual user. Based on these user features the weights in the list of word-weight pairs or weighted keywords which represents the user profile are computed or influenced during the creation of the user profile, and/or a mufti-user profile is split during the creation of an individual user profile from a mufti-user profile, and/or during specification of a suggestion a user history which is used to create the user profile, and/or the user profile, and/or the suggestion results are filtered.Type: GrantFiled: July 22, 2009Date of Patent: June 28, 2011Assignee: Sony Deutschland GmbHInventors: Silke Goronzy, Ralf Kompe, Christian Hying, Zica Valsan, Robert Mencl, Helmut Wais, Thomas Kemp, Sunna Torge, Martin Emele

Publication number: 20040167778Abstract: The present invention relates to a method for recognizing speech, which method leads to an improved recognition rate compared to prior art. Within the method a language model is applied which is based on attribute information of a word, which is descriptive for syntactic and/or semantic information and/or the like of the respective word.Type: ApplicationFiled: February 18, 2004Publication date: August 26, 2004Inventors: Zica Valsan, Martin Emele
