Classification performance of b4,b5,b6,b7 is worse than b3,Is it right?

[wgqbit95]

When I set the input image at a fixed resolution of 256*256, the performance of b3 is better than others. I wonder whether it is the correct condition?

Have you checked the training accuracy? May be the models overfitted the dataset.

It's possible that this is the case if you're not using the resolutions that B4/5/6/7 were trained on.
