Domain Shift

Definition

Difference between development or evaluation conditions and those encountered in operation. Performance should be assessed on material relevant to the intended use and independent of method development. Instruments, specimen types and operating conditions can differ.

Context
Method evaluation

For example, a classifier developed on clean laboratory specimens may perform differently on damaged field material captured with another instrument.

Success on a convenient dataset does not guarantee casework performance. Explain material differences rather than treating every external sample as equivalent validation.
