Classification example
Hi,
I have prepared an example of Xray classification , based on this repo https://colab.research.google.com/drive/1KlKvHDgvi-cfrpJUIOCvczmL4Ctc1wBL
Please check it out. Are you interested in such initiatives?
Hi, we prepared DenseNet model using Pytorch Lightning
https://github.com/PyTorchLightning/lightning-Covid19
@oplatek Several suggestions (just my thoughts during example preparation)
- Metadata have a bunch of useful information; not only covid-19, but other disease labels also - you need to use them for better machine learning model
- Due to class disbalance,
accuracy
is not significant metric - useAUC
orF1 score
instead - Due to low amount of data (only around 100 images) data augmentation is important to prevent overfitting
- Because of medicine field, reproducibility really matters it this case; but this is Catalyst duty
long story short, all these DL best practices were implemented during example preparation, https://colab.research.google.com/drive/1KlKvHDgvi-cfrpJUIOCvczmL4Ctc1wBL Make the world a better with better science :)
@Scitator thank you for the points!
Replacing accuracy is so obvious and it should be there even for the baseline model. -> https://github.com/PyTorchLightning/lightning-Covid19/issues/15
Can you elaborate more on 4? How does Catalyst help reproducibility more than any other framework?
