BreastPathQ: After trianing the model by WSIs, the result which evaluated by Task-specific supervised fine-tuning is bad #7

I am really sorry for the late reply.

In our experiments for BreastPathQ, we have used 69 WSI’s of the training set for pretraining the self-supervised model. I think the issue in your case may be because of 4 WSIs, which were not used.

As the number of patches that can be extracted from a given WSI mainly depends on the tissue content, there might be a high probability that you have lost some significant amount of data for SSL training.

For BreastPathQ, when I used the pretrian model author released and did the finetune, I could get a similar result to your paper.

But I tried to pretrain the model myself, following the instructions (1. Self-supervised pretext task: Resolution sequence prediction (RSP) in WSIs). I used the best pretrain model and did the same things as before. After finetuning, the result was not good enough like paper.

During my training, 4 WSIs which are bad wsis cannot be used. But I don’t think it is an essential problem for me, because just lose hundreds of data.
