  • Patent number: 11727923
    Abstract: A method for conducting a conversation between a user and a virtual agent is disclosed. The method includes receiving, by an ASR sub-system, a plurality of utterances from the user, and converting, by the ASR sub-system, each utterance of the plurality of utterances into a text message. The method further includes determining, by a NLU sub-system, an intent, at least one entity associated to the intent, or a combination thereof from the text message.
    Type: Grant
    Filed: November 24, 2020
    Date of Patent: August 15, 2023
    Assignee: Coinbase, Inc.
    Inventors: Arjun Kumeresh Maheswaran, Akhilesh Sudhakar, Bhargav Upadhyay
  • Patent number: 11586830
    Abstract: A system for reinforcement learning based controlled natural language generation is disclosed. The system includes a token generator subsystem to generate an initial output phrase including a sequence of output tokens. The system includes trained models associated with corresponding predefined tasks. Each trained model includes an attention layer to compute attention-based weights for each output token. The trained models include a scoring layer to generate a phrase sequence level score for the output phrase. The trained models include a reward generation layer to generate dense rewards for each output token based on the attention-based weights and the phrase sequence level score. The trained models include a feedback score generation layer to generate a feedback score based on the dense rewards and reward weights assigned to the dense rewards of the corresponding trained models. The feedback score generation layer provides the feedback score iteratively to the token generator subsystem.
