I've read that turning on and off "no warp" may harm the model. Presuming there must be more than just color correcting happening to mess up the model, what is happening under the hood that harms the model when you mess around with "no warp"?

Thanks.

Warping has nothing to do with color correction.

Warp does what the name suggests.... warps the input a bit. A somewhat extreme example shown here:

The difference between warping and every other augmentation method is that it is only applied to the input. It is not applied to the output. In layman's terms this is to teach the model that it cannot guarantee the same output for any given input, and helps prevent overfitting.

That totally blew my mind. And my preconceived notion of what warping does.

Thank you for that explanation. I thought "warping" was just a generalization for the entire process, and when no warp is applied it just means the "process" is suspended leaving the program to concentrate on color (hence why you leave it for the end.) Your example explains a lot...maybe even worthy of inserting in one of the faqs.
