What does it indicate when a model performs well on car audio in the training set but poorly on car audio in the training dev set?

If both your training set and training dev set contain car audio, you should evaluate your system's performance specifically on that car-audio subset.

If a model does well on car audio in the training set but poorly on car audio in the training dev set, this validates the hypothesis that getting more _____ data would help.

When training and training dev sets both include car-recorded audio, what action should you take to investigate the data mismatch hypothesis?

If a model performs well on car audio in the training set but poorly on car audio in the training dev set, this further validates the hypothesis that getting more car data would help.

If the system does well on car data in the training set but not on car data in the _____, this further validates the mismatch hypothesis.

Match each observation about car-audio subset performance to its implication for the data mismatch hypothesis.

Order the diagnostic steps for using a shared subset (e.g., car audio) to check the data mismatch hypothesis.

What conclusion should you draw if your model achieves high accuracy on car audio in the training set but low accuracy on car audio in the training dev set?

Checking performance on a shared subset in the training and training dev sets can only refute—never further validate—a data mismatch hypothesis.

Ng recommends double-checking the system's performance on the car-audio _____ when both the training and training dev sets include car-recorded audio.

Match each key term in the mismatch hypothesis checking procedure to its correct description.

Order the reasoning steps for deciding whether to collect more car data, starting from suspecting a mismatch to reaching a validated conclusion.
