Visualisations For Challenges
6 Nov. 2020 by James Meakin, Adriënne Mendrik, Maarten van Meersbergen, J.G. Gonzalez and Berend Weel
Visualizations of algorithm results beyond the challenge leaderboard can aid in gaining insight into algorithm performance for a specific task and in finding new research directions. grand-challenge.org offers an option to add visualizations to your challenge through ObservableHQ notebooks. You can use Vega or Vega-lite to easily create graphs and the Vega Editor to edit them, before integrating them in your ObservableHQ notebook that will be embedded in your challenge page on grand-challenge.org. To get you started, we provided a couple of example notebooks for different types of challenges (e.g. a classification, segmentation and detection challenge).

How to build a global, scalable, low-latency, and secure machine learning medical imaging analysis platform on AWS
