Anomaly Detection with Conditioned Denoising Diffusion Models: A. Mousakhan (University of Freiburg)
Arian Mousakhan, a PhD student at the Computer Vision Lab at the University of Freibrug, gave a presentation titled "Anomaly Detection with Conditioned Denoising Diffusion Models" on October 10th 2024 as part of the Visual Intelligence Online Seminar series.
Abstract:
Traditional reconstruction-based visual anomaly detection methods struggle to achieve competitive performance. This is primarily because most existing approaches are unable to precisely reconstruct anomalous inputs resulting in restored pattern that diverge from the original image. Moreover, methods often fail to conduct a robust comparison between the reconstructed and input images. In this paper, we propose Denoising Diffusion Anomaly Detection (DDAD) whereby a generic diffusion model is first trained only on nominal data. During inference, the reverse process is conditioned on the unperturbed input image by correcting the predicted noise at each denoising step. This novel mechanism accurately reconstructs anomalous regions while preserving the in-distribution patterns of the image. Our validate demonstrates the efficacy of DDAD on various datasets, achieving state-of-the-art results

Thanks for sharing
Hi Jon, your talk about deep learning algorithms was interesting this is something I would like to learn more about. Did you apply your experimental models to the k space domain by regressing the images back into the data domain or were you able to use the raw data. I am concern with the pixelated under sampling (discussed at time point~5 min and 40s) is this is not something we could reproduce clinically. We can only fill k space linearly, concentrically or radially. The parallel undersampling is something we could mimic as we can opt to reduce k space filling in the phase encoding direction. I look forward to your response Kind regards Darren
Please can you send me the code for model . Thanks
❤
Inspiring talk, made me see things in a different way!
Nice topic, and very well presented, Tobias!
How does any of this stop the psychopaths taking over humanity from destroying it? Seems to be helping them IMO.
Thank you for the talk. It was super interesting. Cheers!

I find it difficult to understand the speaker's voice.
Thanks for the comment. I did not realize this while speaking, but I agree with your comment. The location of the mic should be readjusted for the next presentation. Hope the generated subtitle helps.
@@Qwertyuiopasdfghjklzxcvbnm266 Thank you for your reply. Yes, the subtitles help a lot.
Great work!
@26:55 what is Y-hat????
Y-hat represents the prediction of the model, while Y representing the ground truth.
I agree that this is a very good talk, and subtitles will help it to reach a wider audience...
really inspiring talk. hope the ppt could be uploaded as well. cheers!
I love this professor's presentation but it can sometimes be difficult to understand what he is saying. It would really help if there was a written transcript of the presentation.

Look forward to more sessions about your current research, Dr. Yu. 🤩
Very interesting talk. Are there any easy to understand sources so I can learn more about the approaches Raul mentioned or about the field in general? So far I have always ignored noisiness of my data when training models.
Thanks for a very nice presentation on the topic!

What sense does image segmentation make as a generative model problem? I imagine you could translate any problem into a generative model problem. E.g. instead of classification we can do generation of class conditioned on input image. Does formulating it in such a way makes more sense for image segmentation than for image classification or was that the point that any problem can be formulated this way?

This is what i need right now, thank you somuch
