Query: Automatic Composition and Optimization of Multicomponent Predictive
  Systems With an Extended Auto-WEKA   Composition and parameterization of multicomponent predictive systems (MCPSs)
consisting of chains of data transformation steps are a challenging task.
Auto-WEKA is a tool to automate the combined algorithm selection and
hyperparameter (CASH) optimization problem. In this paper, we extend the CASH
problem and Auto-WEKA to support the MCPS, including preprocessing steps for
both classification and regression tasks. We define the optimization problem in
which the search space consists of suitably parameterized Petri nets forming
the sought MCPS solutions. In the experimental analysis, we focus on examining
the impact of considerably extending the search space (from approximately
22,000 to 812 billion possible combinations of methods and categorical
hyperparameters). In a range of extensive experiments, three different
optimization strategies are used to automatically compose MCPSs for 21 publicly
available data sets. The diversity of the composed MCPSs found is an indication
that fully and automatically exploiting different combinations of data cleaning
and preprocessing techniques is possible and highly beneficial for different
predictive models. We also present the results on seven data sets from real
chemical production processes. Our findings can have a major impact on the
development of high-quality predictive models as well as their maintenance and
scalability aspects needed in modern applications and deployment scenarios.
