Generation of Machine Learning Outputs Using a Domain Index Matrix to Control a Relative Contribution of Multiple Different Training Data Sets

A system comprising:

• a processor;
• and
• a non-transitory computer-readable medium having stored thereon instructions that, when executed by the processor, cause the processor to perform operations comprising:
• obtaining an input matrix representing one or more features of input data,
• determining a plurality of domain index values that are respectively associated with a plurality of training data distributions,
• generating a domain index matrix comprising the plurality of domain index values,
• providing the input matrix and the domain index matrix to a machine learning model that has been trained to generate output matrices using the plurality of training data distributions that are respectively associated with the plurality of domain index values in the domain index matrix, and
• generating, by the machine learning model and based on the input matrix and the domain index matrix, an output matrix that represents one or more features of output data.
