Code from [ods.ai] Dies Irae team from SIIM-ACR Pneumothorax Segmentation challenge.

Features of the solution:

  • Loss: BCE + DICE. No weighing or log. Just the sum of the losses.
  • Batch 2. Just because
  • A mixture of Unet and Linknet with a backbone from se-resnext50, se-resnext101, SENet154
  • ConvTranspose in decoder
  • Final Convolution 2x2
  • No image normalization at all
  • Sampling in which only batches containing non-zero samples are taken
  • Scheduling: 40 epoch of Adam with CosineAnnealing, 15 epoch of SGD with CyclicLR, 16 epoch of Adam with CosineAnnealing
