An information processing apparatus selects a plurality of interval width sequences of internal knots of a nonuniform B-spline that approximates waveform data, based on a multivariate normal distribution, and then determines a knot vector based on each of the selected interval width sequences and an optimal control point sequence for each knot vector. Also, the apparatus repeats, for a nonuniform B-spline that is defined for each combination of a knot vector and an optimal control point sequence corresponding to the knot vector, the selection of interval width sequences, the determination of knot vectors and optimal control point sequences and the evaluation thereof, until an evaluation whose objective function is minimized is obtained. |
