Patent number: 11617008Abstract: Methods, systems, and computer-readable media for media classification using local and global audio features are disclosed. A media classification system determines local features of an audio input using an audio event detector model that is trained to detect a plurality of audio event classes descriptive of objectionable content. The local features are extracted using maximum values of audio event scores for individual audio event classes. The media classification system determines one or more global features of the audio input using the audio event detector model. The global feature(s) are extracted using averaging of clip-level descriptors of a plurality of clips of the audio input. The media classification system determines a content-based rating for media comprising the audio input based (at least in part) on the local features of the audio input and based (at least in part) on the global feature(s) of the audio input.Type: GrantFiled: March 30, 2021Date of Patent: March 28, 2023Assignee: Amazon Technologies, Inc.Inventors: Tarun Gupta, Mayank Sharma, Xiang Hao, Muhammad Raffay Hamid, Zhitao Qiu

Patent number: 10848791Abstract: Techniques for providing video content are described, where portions of the video content may be determined based an artificial intelligence model. In an example, a computer system may input, to a neural network, a vector representation of a frame. The neural network may be configured based on an error of associating the frame with an incorrect category. The error may be based on timing of the frame and on an error time margin relative to a start time or an end time of the incorrect category. The computer system may receive back an association between the vector representation and a category and may generate, based on the association, an identifier of a portion of the video content. The identifier may associate the portion of the video content with the category and identify a start time or an end time of the portion of the video content.Type: GrantFiled: October 30, 2018Date of Patent: November 24, 2020Assignee: Amazon Technologies, Inc.Inventors: Vernon Germano, Xiang Hao, Kripa Kanchana Sivakumar, Benjamin Cheung

Publication number: 20110173452Abstract: The present invention constructs a compound type combined public key system on the basis of a combined public key CPK system. The combined key is combined by an identity key and a randomly defined key. The randomly defined key can be defined by a center, called a system key; and can be self-defined, called updating key. Combination of the identity key and the system key generates a first-order combined key. The first-order combined key is then combined with the updating key to generate a second-order combined key. The first-order combined key can be used for centralized digital signature and key exchange. The second-order combined key can be used for distributed digital signature, to provide individual with convenient key exchange and absolute privacy. A combining matrix, as a trust root, provides proof of integrity of identity and key, with no need of third party proof.Type: ApplicationFiled: May 27, 2009Publication date: July 14, 2011Inventors: Xiang-hao Nan, Huaping Chen
