Claim 0:
1. A computer-implemented method comprising:
generating, using a first machine learning (ML) model configured to perform natural language processing first output data responsive to a first user input, wherein the first ML model is associated with a first hyper-parameter having a first value;
determining the first output data corresponds to an undesired response to the first user input;
based at least in part on determining the first output data corresponds to the undesired response to the first user input, generating a second ML model corresponding to the first ML model, wherein the second ML model is associated with the first hyper-parameter having a second value instead of the first value;
processing a first set of user inputs using the second ML model;
determining a first metric value corresponding to processing of the first set of user inputs using the second ML model;
determining a number of values to test for the first hyper-parameter;
determining the number of values is satisfied by processing of the first set of user inputs using the second ML model; and
based on the first metric value and the number of values being satisfied, storing the second ML model for processing of future user inputs.
