Patent number: 12639948Abstract: A system and method for video temporal action proposal generation are provided. It processes video features extracted from the input video through an encoder to obtain video encoding features with global information, extracts corresponding interest segment features from the video encoding features using pre-trained proposal segments, and provides them to the decoder. The decoder generates segment features based on the interest segment features corresponding to each proposal segment and the pre-trained proposal features. These are then provided to the prediction module, generating temporal action proposal results based on the decoder's segment features. The solution in embodiments of the present invention can effectively capture global context information of the video, obtaining video encoding features with stronger representational capabilities.Type: GrantFiled: August 19, 2022Date of Patent: May 26, 2026Assignees: University of Hong Kong Versitech Limited, TCL Technology Group CorporationInventors: Ping Luo, Jiannan Wu, Jiajun Shen, Lan Ma

Patent number: 12334068Abstract: Approaches are generally described for corrupted speech detection in voice-based computer interfaces. First input data including first audio data representing a user utterance may be received. First data representing the first audio data may be generated using a first encoder. First text data representing a transcription of the user utterance may be generated. Second data representing the first text data may be generated using a second encoder different from the first encoder. Third data may be generated by combining the first data and the second data. The third data may be sent to a classifier network trained to predict a relevant corruption state for speech processing inputs. The classifier network may determine that the first input data corresponds to a first corruption state.Type: GrantFiled: September 29, 2022Date of Patent: June 17, 2025Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Di Wang, Deshen Wang, Lan Ma, Shu Wang, Wenbo Yan, Prathap Ramachandra
