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
