  • Publication number: 20250111104
    Abstract: An information processing apparatus selects an excluded element set that is a subset of a tentative element set, from the tentative element set that is at least a part of a solution target element set constituting an optimization problem as a solution target, determines whether or not a tentative mathematical model that is a mathematical model in which an element set excluding the excluded element set from the tentative element set and a constraint condition are formulated, is feasible, in a case where the tentative mathematical model is determined to be infeasible, extracts a list of constraint conditions conflicting with each other from the tentative mathematical model, converts each constraint condition of the extracted list into a name of the constraint condition, and outputs the name of the constraint condition obtained by conversion.

  • Patent number: 7864967
    Abstract: According to one embodiment, various feature parameters are calculated for distinguishing between a speech and music and between music and background sound for an input audio signal. With the feature parameters, score determination is made as to whether the input audio signal is close to a speech signal or a music signal. If the input audio signal is determined to be close to music, the preceding score determination result is corrected considering the influence of background sound. Based on the corrected score value, a sound quality correction process for a speech or music is applied to the input audio signal.

  • Patent number: 7856354
    Abstract: According to one embodiment, various characteristic parameters for determining whether an input audio signal is a voice signal or a music signal are calculated and the calculated characteristic parameters are compared with a threshold value for voice determination and a threshold value for music determination. A voice characteristic score is provided to a characteristic parameter indicating voice and a music characteristic score is provided to a characteristic parameter indicating music. Then, based on a difference between a sum total of voice characteristic scores and a sum total of music characteristic scores, it is determined whether the input audio signal is a voice signal or a music signal.
