An improved version of Turbo algorithm for the Black-box optimization (BBO) competition organized by NeurIPS 2020
This implemention is our solution for the BBO competition organized by NeurIPS 2020 conference: https://bbochallenge.com/
Final results
Our algorithm ranked the 4th place on the “warm start friendly” leaderboard: https://bbochallenge.com/altleaderboard It also ranked 17th place on the final leaderboard: https://bbochallenge.com/leaderboard
Result on “warm start friendly” leaderboard
Main contributions
- Reduce the bounds of hyper-parameters of each machine learning classifier
- Improve the diversity in selecting batch elements
- Increase the number of explored trust regions by using a base-length decay
