摘要

The composition by AI can be realized more easily than in the prior art.Solution: an initialization processing part 212 for preparing n models 61 each having different initial values of parametersA posteriori probability computing unit 214 for performing a calculation process for calculating a probability of appearance appearing in each of the plurality of models 61 in each of the prepared plurality of music data 60 andA parameter update section 215 for performing adjustment processing for adjusting the parameters of each of N models 61 based on the probability of appearanceA convergence determination unit 216 determines whether or not a predetermined condition has been satisfied.AndA posteriori probability calculating Part 214 and a parameter update part 215RespectivelyBy alternately performing the calculation processing and the adjustment process until the predetermined condition is satisfiedN styles each produces a music model.Diagram
