ROC-AUC on Mvtec

Hello Alessio,
I'm Emilie, a PhD student in deep learning. I'm really interested in the anomaly detection model, and FastFlow seems really promising. I'm trying to develop my own version to make it work on medical images inspired by the following repo:

• yours of course ;)
• https://github.com/openvinotoolkit/anomalib/tree/feature/fastflow/anomalib/models/fastflow
• https://github.com/openai/glow
  Using your implementation, I can't reproduce the results of the article. So I would like to know if I can't get it to work properly or if you are still working on it and haven't managed to reproduce them yet.
  Thank you for your great work!

Hi Emilie!
I haven't managed to reproduce them yet, but others had some progress,
I'm currently working on my Master thesis and, since I couldn't reproduce the results of the paper, I had to use another neural network, so I can't work on this project at this moment. The neural network I'm using is CS-Flow. It was created by the same author of Differnet, which I used in this repository as a starting point. I'm getting good results, so I advice you to use this one if you want to use Normalizing Flows.
The great problem with FastFlow is that there are ambiguities in the paper, so it's hard to implement. Look at the Q&A in the issues of this repo if you want to know more. There are some great guys who did some progress in solving these ambiguities,
Good luck for you PhD! Working on medical images is a noble mission, and contributing to OpenAI is really cool. I'm almost envious! ;)
Best,
Alessio

The Q&A gives great input I did not see this! Thank you and good luck with your thesis :)
