Classification: CPC G | IPC G

Claim 10:
11. The system of claim 10, wherein the processor is further configured to:
generate a plurality of sequential predicted keywords based on the first source token set keyword probability distribution of the copy data model architecture associated with a probability of generating the keyword from the first source token set, based on a respective plurality of sequential source tokens of the first data set, and a second set keyword probability distribution of the generation data model architecture, based on the respective plurality of sequential source tokens of the first data set, and associated with the probability of generating the keyword from the second data set;
update the plurality of parameters by,
sequentially, for each ground truth token associated with the respective plurality of sequential source tokens of the first data set:
determining the generation loss based on comparing the respective ground truth token to the first exclusion list of ground truth tokens;
determining the copy loss based on comparing the predicted keyword to a second exclusion list of source tokens and ground truth tokens; and
adjusting the plurality of parameters based on the copy loss, the generation loss, and a comparison of the predicted keyword and a respective predicted keyword ground truth token to penalize the decoder for generating repetitive keywords.
