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
