Actual exam question for ISTQB's CT-AI exam
Question #: 89
Topic #: 10
Which ONE of the below is MOST likely to indicate a problem with underfitting in an ML model?

Suggested Answer: D Vote an answer

Underfitting occurs when the model is too simplistic to capture the underlying patterns in the training data. This results in poor performance not only on new data but also on the data it was trained on. Thus, if the model is inaccurate on data similar to the training data, it suggests underfitting.
