Generation of machine learning model lineage events

A system having one or more computer processors, the system configured to:

• identify a machine learning model with missing lineage;
• generate a creation event and deployment event for the machine learning model;
• generate a batch scoring event for the machine learning model, wherein generating the batch scoring event comprises:
• identifying an amount of target batch records for each target batch and an amount of source batch records for each source batch for the machine learning model,
• comparing the amount of source batch records for each source batch,
• determining, based on the comparing, whether a plurality of source batch records have an equal amount of records, and
• mapping, based on the determining, each source batch to each corresponding target batch;
• and
• create a lineage path for the machine learning model based on the creation event, the deployment event, and the batch scoring event.

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a server to cause the server to perform a method, the method comprising:

• identifying a machine learning model with missing lineage;
• generating a creation event and deployment event for the machine learning model;
• generating a version change event for the machine learning model, wherein generating the version change event comprises:
• identifying one or more predicted data points with a low model confidence,
• rescoring the one or more predicted data points based on the machine learning model at a second time period, resulting in updated one or more predicted data points,
• determining that the updated one or more predicted data points are significantly different than the one or more predicted data points, and
• inferring, based on the determining, that there is a new version of the machine learning model;
• and
• creating a lineage path for the machine learning model based on the creation event, the deployment event, and the version change event.
