Scheduler

• GradualWarmupSchedulerV2 (https://www.kaggle.com/code/underwearfitting/single-fold-training-of-resnet200d-lb0-965)

TTA

Rotations :
    - 90
    - 180
    - 270

Add mixup

https://arxiv.org/abs/1710.09412

Add 4 folds

2-nd scroll has been divided into two folds

Final Solution

- UnetMeanpooled 4folds
- 32 channel from 16 to 48 with stride 2
- TTA rotations
- GradualWarmupSchedulerV2
- 8 models in total (4 with best CV F_0.5 and 4 with best BCE)
