# 2nd place Solution I trained on train images only. My attempts with pseudo labeling on extra-images did not work. The reason for this is likely the lack of experimentation or quite possibly my incompetence. I used 6fold seresnext 101 lr: 2e-4 batch size: 16 input size: 448x448x3 epochs: 5 augmentations: standard tta: 8x cv: ~0.92 By averaging folds, it scored 0.927+ on public lb and 0.935+ on private lb. My CV improvements did not reflect on LB. I believe strongly that training data is noisy.
