Publication number: 20230351753Abstract: A text-video recommendation model determines relevance of a text to a video in a text-video pair (e.g., as a relevance score) with a text embedding and a text-conditioned video embedding. The text-conditioned video embedding is a representation of the video used for evaluating the relevance of the video to the text, where the representation itself is a function of the text it is evaluated for. As such, the input text may be used to weigh or attend to different frames of the video in determining the text-conditioned video embedding. The representation of the video may thus differ for different input texts for comparison. The text-conditioned video embedding may be determined in various ways, such as with a set of the most-similar frames to the input text (the top-k frames) or may be based on an attention function based on query, key, and value projections.Type: ApplicationFiled: August 24, 2022Publication date: November 2, 2023Inventors: Satya Krishna Gorti, Junwei Ma, Guangwei Yu, Maksims Volkovs, Keyvan Golestan Irani, Noël Vouitsis

Publication number: 20220335718Abstract: A video localization system localizes actions in videos based on a classification model and an actionness model. The classification model is trained to make predictions of which segments of a video depict an action and to classify the actions in the segments. The actionness model predicts whether any action is occurring in each segment, rather than predicting a particular type of action. This reduces the likelihood that the video localization system over-relies on contextual information in localizing actions in video. Furthermore, the classification model and the actionness model are trained based on weakly-labeled data, thereby reducing the cost and time required to generate training data for the video localization system.Type: ApplicationFiled: April 8, 2022Publication date: October 20, 2022Inventors: Junwei Ma, Satya Krishna Gorti, Maksims Volkovs, Guangwei Yu

Publication number: 20220318617Abstract: The disclosed embodiments include computer-implemented systems and methods that dynamically predict future occurrences of events using adaptively trained machine-learning or artificial-intelligence processes. For example, an apparatus may generate an input dataset based on elements of interaction data associated with an extraction interval. Based on an application of a trained artificial intelligence process to the input dataset, the apparatus may generate output data representative of a predicted likelihood of an occurrence of a first event during a first portion of a target interval, which may be separated from the extraction interval by a second portion of the target interval. The first event may be associated with a predetermined temporal duration within the first portion of the target interval. The apparatus may transmit a portion of the generated output data to a computing system, and the computing system may be configured to perform operations based on the portion of the output data.Type: ApplicationFiled: June 2, 2021Publication date: October 6, 2022Inventors: Anson Wah Chun WONG, Junwei MA, Maksims VOLKOVS, Tomi Johan POUTANEN
