  • Patent number: 11929070
    Abstract: Techniques for performing centralized unsuperivised learning in a multi-domain system are described. A user may request labeled data for an ML task, where the request includes a prompt for obtaining relevant explicit user feedback. The system may use the prompt to collect explicit user feedback for relevant runtime user inputs. After a duration of time (in the user's request for labeled data) has elapsed, the system determines whether collected user feedback indicates processing of the user input was defective and, if so, determines a cause of the defective processing. The system then uses one or more label generators to generate labeled data using the collected user feedback, whether the processing was defective, and the determined defect cause.

  • Publication number: 20240004782
    Abstract: Debug engine receives a capture file over the network interface and initiate playback by executing the capture file with the processor. The capture file comprises real-time local network environment video synchronized with data captured by a local browser at a local station interacting with a local network gateway device over a local network. The capture file is played back, using a mock server including transmitting HTTP requests from the capture file at the developer station to the mock gateway server. Additionally, HTTP responses are received from the capture file at the mock gateway server, in synch with actions in the real-time local network environment video. A GUI engine renders a GUI on the developer computer from real-time GUI code generated from the capture file playback as modified by processing the HTTP responses.
