Forget the other chat, but agree with a comment re the number of samples in test (it's not much!). So there will be a big difference here and probably a big shake up in the end. Seems like a gamble to me haha

EfficientNet-B0 is lightweight. Good baseline, but not optimal.

Trees Hate You Try:

  • EfficientNet-B4 or B5
  • ConvNeXt
  • Swin Transformer

Even a single upgrade here can outperform heavy tuning on B0.
