Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A computer system comprising:
a processor operatively coupled to memory; and
an artificial intelligence (AI) platform, in communication with the processor, having machine learning (ML) tools, the tools comprising:
a machine learning model (MLM) manager configured to:
access a plurality of pre-trained 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; and
for each of the source MLMs, generate associated labels from the inputted data objects;

a metric manager configured to, for each of the source MLMs, calculate a metric reflecting a similarity between the labels of the test dataset and the generated labels;
the MLM manager further configured to select a base MLM to be used for transfer learning from the plurality of source MLMs based upon the calculated metric;
a training manager configured to train the selected base MLM with a target dataset for the target domain; and
the MLM manager further configured to capture knowledge of the selected base MLM, including:
use a context representation layer of the selected base MLM; and
replace a classification layer of the selected base MLM with a new classifier mapped to space of the target dataset,

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.
