Testing AI-Specific Quality Characteristics

In a coffee-producing region of Colombia, weather storms have caused substantial production losses. This has led to a major decline in the stock prices of coffee bean-producing companies.

Which ONE of the following testing types SHOULD be performed for an ML stock-price prediction model to detect the effect of a phenomenon such as the one described on coffee stock prices?

Explanation

Concept-drift testing detects changes over time in the underlying data distribution or in the relationship between model inputs and the target outcome. Weather-driven production losses can alter the factors that influence coffee-company stock prices, so the model’s learned relationship may no longer remain valid.
