Will MixUp callback be applied at test time if I call learn.TTA?

I am using MixUp via callback like so

learn.fit(1, cbs=[MixUp(0.2)])

Will learn.tta() be set up to apply mixup by default ? If not, how do I ensure mixup is applied in TTA ?

MixUp is a augmentation / regularization technique. that means by using MixUp during training, you can avoid overfitting, train your model longer and thus increase the accuracy. This is done by combining two imputs / outputs during training. see https://docs.fast.ai/callback.mixup.html#MixUp

MixUp can not be applied during inference / prediction. Hope that helps.
