Classification: CPC G | IPC G

Claim 5:
6. A computer program product to utilize machine learning to facilitate transfer learning, the computer program product comprising:
a tangible computer readable storage medium having program code embodied therewith, the program code executable by a processor to:
access a plurality of pre-trained source machine learning models;
for each of the source MLMs:
input a plurality of data objects of a test dataset into each of the source MLMs, the test dataset comprising the plurality of data objects associated with labels;
generate associated labels from the inputted data objects; and
calculate a metric reflecting a similarity between the labels of the test dataset and the generated labels;

select a base MLM to be used for transfer learning from the plurality of source MLMs based upon the calculated metric; and

train the selected base MLM with a target dataset for the target domain,
wherein program code is executable by the processor to capture knowledge of the selected base MLM, including:
use a context representation layer of the selected base model; and
replace a classification layer of the selected base model with a new classifier mapped to space of the target dataset, and

wherein the calculated metric is limited to a position of a returned output, and the position is selected from a span, a bounding box, or a location.
