Exam Certified Machine Learning Associate topic 1 question 10 discussion

A. This is incorrect because the training time is generally determined by the pipeline complexity and the data size, not by the cross-validation object placement. C. This is incorrect. The parallelism=2 parameter still allows parallel processing, and the placement of the cross-validation object doesn’t impact parallelization. D. This is incorrect as reproducibility depends on the seed parameter, which is set to 42 here. Moving the cross-validator in the pipeline does not inherently affect reproducibility. E. This is incorrect. Moving the cross-validator object does not affect the number of times the model is refit in each fold.
