Assignee: KABUSHIKI KAISHA TOSHIBA
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A parameter vector value proposal apparatus, comprising:
a storage device that stores observation data, which is a set of pairs each consisting of a parameter vector value representing a point in a D-dimensional space (D is an integer of 2 or more) and an observation value of an objective function at the point; and
processing circuitry configured to:
determine, as a low-dimensional search space, an R-dimensional affine subspace (R is an integer that is not less than 1 and less than D) that passes through a point represented by a predetermined parameter vector value in the D-dimensional space;
extract, as extracted data, a set of pairs corresponding to one or more points at which similarity to a point included in the low-dimensional search space are equal to or more than a predetermined value, the one or more points being among one or more points in the D-dimensional space represented by one or more parameter vector values included in the observation data stored in the storage device; and
propose a parameter vector value representing a point at which a value of the objective function is to be observed next, based on the extracted data.
