Claim 6:
7. The parameter vector value proposal apparatus according to claim 1, wherein
a kernel function that calculates the similarity has a length scale vector as a hyperparameter; and
the processing circuitry is further configured to:
refer to one or more points in the D-dimensional space represented by the one or more parameter vector values included in the observation data stored in the storage device, and extract, as the extracted data, a set of pairs corresponding to one or more points at which a square of a normalized Euclidean distance to a point included in the low-dimensional search space is equal to or less than a predetermined value, and
in the calculation of the square of the normalized Euclidean distance, adopt a value of each element of the length scale vector as a standard deviation corresponding to each coordinate axis direction of the D-dimensional space.
