Abstract: A computing device receives factor information indicating multiple factors (e.g., hyperparameters for designing a system comprising a machine learning algorithm). The computing device receives range information indicating initial ranges with a range for each of possible options for the multiple factors. The computing device obtains a space-filling design for the design space. The space-filing design indicates selected design points in the design space.

The computing device generates, based on the space-filling design, an initial design suite that provides initial design cases corresponding to one or more of the selected design points. The computing device generates evaluations of the initial design cases. The computing device outputs, based on the evaluations of the initial design cases, an indication of a selected design case.

Abstract: A computing device generates representative points, each representing a potential design point for a design space. The computing device determines for the design space primary clusters, a categorical factor, and at least two levels for the categorical factor. The computing device, for each of the primary clusters, selects a design point from each sub-cluster of the respective primary cluster. The computing device, for each of the primary clusters, allocates the at least two levels of the categorical factor, such that a level of the at least two levels is allocated to each selected design point in the respective primary cluster. The computing device modifies an initial sub-design that represents the selected design points allocated a given level of the categorical factor by increasing separation between design points allocated a same level of the categorical factor. The computing device outputs to an output device a modified design for the design space.
