WebIn this tutorial, we show how to implement B ayesian optimization with a daptively e x panding s u bspace s (BAxUS) [1] in a closed loop in BoTorch. The tutorial is purposefully similar to the TuRBO tutorial to highlight the differences in the implementations. This implementation supports either Expected Improvement (EI) or Thompson sampling (TS).
