SIG webinars


This webinar series by the SIG for Challenges aims to educate medical imaging researchers on how to successfully participate in and conduct challenges. A particular focus will be placed on issues of quality control and validation using appropriate metrics from the organizers' and participants’ points of view.

Two webinars were organized so far:

(1) How to win a challenge (July 2022)

The recording of the webinar can be found online under this link.

Invited speakers:

Dr. Fabian Isensee has consistently enabled the translation of state-of-the-art algorithms into real-world applications, represented by nnU-Net, the de-facto standard for segmentation in the medical domain. The methods he developed have won multiple international segmentation competitions.

Dr. James Howard is an academic cardiologist who has published numerous research papers using AI to interpret X-rays, cardiac ultrasound, ECG, MRI and cardiac pressure waveforms. He has entered several Kaggle competitions, including the Deepfake Detection Challenge, where he won a gold medal and a $40,000 prize, against 2200 other teams.

(2) How to run a challenge (October 2022)

The recording of the webinar can be found online under this link.

Challenge platforms:

https://grand-challenge.org/ is an open source platform for running challenges. Recently added features include the possibility for challenge participants to upload algorithms that solve a challenge and give other users access to these algorithms to process their own data. Bram van Ginneken, Kiran Vaidhya Venkadesh and Anindo Saha will present how to use the platform for organizing high-profile challenges. The slides of the talk are available from the following link:  grand-challenge-slides.pdf

https://www.synapse.org/ is an open collaboration platform developed by Sage Bionetworks.  Synapse is the main platform supporting DREAM Challenges (dreamchallenges.org). Jake Albrecht from Sage will present tips for challenge organizers on how to define a successful community challenge, with examples from Synapse.
