โ€‹โ€‹SAUNet: Shape Attentive U-Net for Interpretable Medical Image Segmentation

New approach for interpreting medical image segmentation models.

U-Net and other image segmentation models work quite well on medical data, but still aren't widely adopted. One of the reasons is the lack of reproducibility as well as robustness issues.
The key idea of the paper is using the additional stream in U-Net with shape features to increase robustness and use the output of this stream (attention map) that can be used or interpretability.

Modifications to the basic U-Net architecture:
- use dense blocks from DenseNet-121 as the encoder.
- use dual attention decoder block (with spatial and channel-wise attention paths)
- make the second stream using object shape (contour)
- dual-task loss function: cross-entropy + dice + edge loss (bce loss of the predicted shape boundaries)

Shape and spatial attention maps can be used for interpretation.

Live U-Net implementation online session today

Famous Abhishek Thakur (First 4x GM on Kaggle) is going to show you how to implement the original U-Net with #PyTorch.

Session starts in 4 hours from now (at 6PM CET / 9.30PM IST), make sure you turned the notifications on if you are interested.

๐Ÿฆœ Hi!

We are the first Telegram Data Science channel.


Channel was started as a collection of notable papers, news and releases shared for the members of Open Data Science (ODS) community. Through the years of just keeping the thing going we grew to an independent online Media supporting principles of Free and Open access to the information related to Data Science.
