TK-MARS: An Efficient Approach for Deterministic and Stochastic Black-Box Optimization

Simulators can be used to study, and potentially optimize many real-world complex systems that may either be computer simulators such as air quality, green building design, simulation model of a hospital emergency room, investment portfolio for financial planning or actual experiments like vehicle crash testing, and agricultural crop ideotype simulation models that are called black-box systems. 

Since these simulators are often computationally too expensive to be embedded directly within a global optimization method, a more practical approach would be to employ less computationally expensive surrogate models. Surrogate optimization for black-box systems requires careful selection of simulator runs, so as to simultaneously improve the surrogate model and gain more information on the optimum location in each iteration. Historically, surrogate optimization methods assume the complex system involves no uncertainty in performance and the set of important decision variables is known apriori. In the real world, both of these assumptions are violated. To this end, my research has introduced a new black-box optimization paradigm, to address uncertainty in system performance and feature selection for important decision variables. 

My research objective is to generalize the propelled discovery techniques to any large-scale black-box systems. More importantly, my examination in black-box optimization has the potential to contribute to the challenging problem of hyper-parameter tuning as fundamental progress towards democratizing machine learning.
