Engineered Decision Tree for Judging Spacecraft Collision Risks

Sven Rebhan and Nils Einecke, "Engineered Decision Tree for Judging Spacecraft Collision Risks", 8th European Conference on Space Debris, 2021.


In this talk, we will summarize our insights gathered during the ESA space collision avoidance challenge that took place end of 2019. After applying a wide set of techniques and algorithms we came to the conclusion that the structuring of train and test hampers automatic regression or machine learning. Thus, we rather implemented a step-by-step pipeline that is based on statistical and data analysis of the available data. This manual engineered pipeline was ranked overall first after the end of the competition.
