[All AIP-210 Questions]

Which of the following is NOT a valid cross-validation method?

Show Suggested Answer Hide Answer
Suggested Answer: D

Stratification is not a valid cross-validation method, but a technique to ensure that each subset of data has the same proportion of classes or labels as the original data. Stratification can be used in conjunction with cross-validation methods such as k-fold or leave-one-out to preserve the class distribution and reduce bias or variance in the validation results. Bootstrapping, k-fold, and leave-one-out are all valid cross-validation methods that use different ways of splitting and resampling the data to estimate the performance of a machine learning model.

Wait, is stratification really not a valid method? That seems off!

I thought stratification was just a way to split data, not a method!

I feel like Stratification is related to ensuring class balance, but I can't recall if it's considered a cross-validation method or not.

I practiced a similar question where we had to identify valid methods, and I remember that K-fold is definitely valid.

I think Bootstrapping is more of a resampling technique rather than a cross-validation method, but I could be wrong.

I remember discussing K-fold and Leave-one-out methods in class, but I'm not sure about Stratification being a cross-validation method.

Bootstrapping is the only one on this list that's not a true cross-validation method, so that's got to be the correct answer.

Hmm, I'm a little unsure about this one. I know k-fold, leave-one-out, and stratification are all common cross-validation techniques, but I can't remember if bootstrapping is valid or not.

I'm pretty sure bootstrapping is a valid cross-validation method, so I'll eliminate that one.

Okay, let me think this through. Bootstrapping involves resampling the data with replacement, which is different from the traditional cross-validation methods. I'll go with that as the answer.

I think commercial filings would be the most likely to have the ownership information I need to solve this case. That's my best guess.
