CEC-2019 Workshop on Data-driven Optimization and Applications (DDOA 2019)

Scope and aim:
Not all objective functions can be formulated using explicit equations, instead, they are normally evaluated using high precise simulation or computationally expensive experiments. So although meta-heuristic algorithms, including evolutionary algorithms and swarm optimization, have been paid more and more attention in real-world applications, they are limited for optimizing those problems with time-expensive performance evaluation on the design. Recently, the historical data are proposed to be utilized to train surrogate models using machine learning techniques in order to replace the compute-expense/time-expensive objective function during phases of the heuristic search. The successful applications can be found in aerodynamic design, structural design, drug design, and so on.
Despite surrogate-assisted meta-heuristic algorithms get successful application, there still remain many challenges for researchers to explore. For example, due to the curse of dimensionality and the insufficiency of the samples for model training, it is very difficult, if not impossible to train accurate surrogate models. Thus, appropriate model management techniques based on the characteristics of meta-heuristic algorithms play significant important role in the surrogate-assisted optimization. In addition, modern data analytics involving advance sampling techniques and learning techniques such as semi-supervised learning, transfer learning and active learning are highly beneficial for speeding up evolutionary search while bringing new insights into the problems of interest. Finally, the application problems for verifying the efficiency and effectiveness of different approaches are also indispensability.
This workshop aims to promote the research on data-driven optimization and extend meta-heuristic algorithms to solve time-expensive problems.
