Hangar, an open-source system created by American Airlines, helps manage hackathons. The team proposed an algorithm for recommending the winning teams using the “Multi-armed Bandits for Pairwise Comparison” approach, based on two policies: “Epsilon-Greedy” and “Upper Confidence Bound.” Research area: AI, ML, NLP
Jupyter notebooks can only restore code and outputs in the event of failure, but not variable contents and the internal state of the Python interpreter. Using FastFreeze in Kubernetes, created by TwoSigma, the team improved checkpointing and restoring. Research area: Systems.
