WITH THE BAYESIAN OPTIMIZATION ALGORITHM by Moshe Looks

By Moshe Looks B. Sc, Saint Louis and Missouri Washington University

Abstract

The hierarchical Bayesian Optimization Algorithm (hBOA) [24, 25] learns bitstrings by constructing explicit centralized models of a population and using them to generate new instances. This thesis is concerned with extending hBOA to learning open-ended program trees. The new system, BOA programming (BOAP), improves on previous probabilistic model building GP systems (PMBGPs) in terms of the expressiveness and open-ended flexibility of the models learned, and hence control over the distribution of individuals generated. BOAP is studied empirically on a toy problem (learning linear functions) in various configurations, and further experimental results are presented for two real-world problems: prediction of sunspot time series, and human gene function inference.
