Assignee: ROYAL BANK OF CANADA
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 3:
4. The system of claim 2, wherein the processor is further configured to train the model by:
determining a second predicted future keyword by processing a third source token and third truth token with the future sequence predictor;
and wherein updating the plurality of parameters further includes:
updating the first exclusion list with the respective predicted future keyword ground truth token;
updating the second exclusion list with the respective predicted future keyword ground truth token and a second source token associated with the respective predicted future keyword ground truth token;
determining a second future copy loss based on comparing the second predicted future keyword to second exclusion list of source tokens and ground truth tokens;
determining a second future generation loss based on comparing the predicted future keyword to the first exclusion list of ground truth tokens and source tokens; and
adjusting the plurality of parameters based on a decayed value of the second future copy loss, the second future generation loss, and a comparison of the second predicted future keyword and a respective second predicted future keyword ground truth token to penalize the decoder for generating repetitive keywords.
