Hmm, I'm not convinced. Model B may be simpler, but it's still got a pretty decent accuracy on the validation data. I'd go with the simpler model, it's less likely to have issues with overfitting.

I think Model A is the better choice. Sure, it has a higher accuracy on the training data, but that's probably because it's more complex and able to overfit the training set. The validation data is a better representation of real-world performance, and Model A does better there.

That's true, but Model A is more complex and performs better on the training data boundary.

But Model B has higher accuracy on the validation data, so maybe we should consider that.

I think we should select Model A because it has higher accuracy on the training data.
