Patent number: 11295171Abstract: A MapReduce-based training framework exploits both data parallelism and model parallelism to scale training of complex models. Particular model architectures facilitate and benefit from use of such training framework. As one example, a machine-learned model can include a shared feature extraction portion configured to receive and process a data input to produce an intermediate feature representation and a plurality of prediction heads that are configured to receive and process the intermediate feature representation to respectively produce a plurality of predictions. For example, the data input can be a video and the plurality of predictions can be a plurality of classifications for content of the video (e.g., relative to a plurality of classes).Type: GrantFiled: October 18, 2019Date of Patent: April 5, 2022Assignee: GOOGLE LLCInventors: Joonseok Lee, Balakrishnan Varadarajan, Ariel Gordon, Apostol Ivanov Natsev, Seong Jae Hwang

Patent number: 9177209Abstract: A computer implemented method, apparatus, and computer program product code for temporal, event-based video fingerprinting. In one embodiment, events in video content are detected. The video content comprises a plurality of video frames. An event represents discrete points of interest in the video content. A set of temporal, event-based segments are generated using the events. Each temporal, event-based segment is a segment of the video content covering a set of events. A time series signal is derived from each temporal, event-based segment using temporal tracking of content-based features of a set of frames associated with the each temporal, event-based segment. A temporal segment based fingerprint is extracted based on the time series signal for the each temporal, event-based segment to form a set of temporal segment based fingerprints associated with the video content.Type: GrantFiled: December 17, 2007Date of Patent: November 3, 2015Assignee: SINOEAST CONCEPT LIMITEDInventors: Jane Wen Chang, Apostol Ivanov Natsev, John R.

Patent number: 8032539Abstract: The present invention is directed to a method and apparatus for assisting in rating and filtering multimedia content, such as images, videos and sound recordings. One embodiment comprises a computer implemented method for rating the objectionability of specified digital content that comprises one or more discrete content items, wherein the method includes the step of moving the specified content to one or more filtering stages in a succession of filtering stages. After the specified content is moved to a given one of the filtering stages, a rating procedure is carried out to determine whether a rating can be applied to one or more of the content items, and if so, a selected rating is applied to each of the one or more content items. The method further comprises moving content items of the specified content to the next stage in the succession after the given stage, when at least one content item of the specified content remains without rating, after the rating procedure at the given stage.Type: GrantFiled: March 11, 2008Date of Patent: October 4, 2011Assignee: International Business Machines CorporationInventors: Shahram Ebadollahi, Milind Naphade, Apostol Ivanov Natsev, John Richard Smith, Ioana Roxana Stanoi, Jelena Tesic, Lexing Xie

Patent number: 7788099Abstract: A computer implemented method, apparatus, and computer usable program code for multimodal cross-vocabulary mapping. A corpus of multimodal content is annotated simultaneously using annotations from a plurality of vocabularies to form a set of common annotations. Relationships between a first vocabulary associated with a first modality and a second vocabulary associated with a second modality are identified using the set of common annotations to form a multimodal vocabulary mapping. Items in the first vocabulary associated with the first modality are mapped to items in the second vocabulary associated with the second modality using the multimodal vocabulary mapping.Type: GrantFiled: April 9, 2007Date of Patent: August 31, 2010Assignee: International Business Machines CorporationInventors: Alexander Haubold, Milind R.

Patent number: 6906719Abstract: A visual query system, and associated method and computer program product enhance and accelerate content-based querying, and present a new image similarity measure using known or available software applications and hardware components of video compression systems. The present system encodes images as consecutive frames in a video sequence and uses the ratio between the file length of the compressed sequence and the original file length as a distance measure. The system considers the compression ratio to be an estimate of the entropy of the combined images, which can be used to estimate the amount of new information introduced from one image to the other.Type: GrantFiled: October 12, 2002Date of Patent: June 14, 2005Assignee: International Business Machines CorporationInventors: Atul Chadha, Balakrishna Raghavendra Iyer, Apostol Ivanov Natsev

Patent number: 6751363Abstract: Methods of imaging objects based on wavelet retrieval of scenes utilize wavelet transformation of plural defined regions of a query image. By increasing the granularity of the query image to greater than one region, accurate feature vectors are obtained that allow for robust extraction of corresponding regions from a database of target images. The methods further include the use of sliding windows to decompose the query and target images into regions, and the clustering of the regions utilizing a novel similarity metric that ensures robust image matching in low response times.Type: GrantFiled: August 10, 1999Date of Patent: June 15, 2004Assignee: Lucent Technologies Inc.Inventors: Apostol Ivanov Natsev, Rajeev Rastogi, Kyuseok Shim
