Abstract: Provided is a process including: searching code of a machine-learning pipeline to find a first and a second object code sequences performing similar tasks; modifying the code of the machine learning pipeline by inserting a third object code sequence into the code of the machine learning pipeline, the third code sequence being operable to pass control to the first object code sequence; inserting a branch at the end of the first code sequence, the branch being operable to: pass control, upon detection of a first predefined condition, to an instruction following the first object code sequence, and to pass control, upon detection of a second predefined condition, to an instruction following the third object code sequence; and wherein the third code sequence is executed in place of the second object sequence without affecting completion of the tasks.
