Abstract:
The present invention relates to an information processing apparatus, an information processing method, and a program capable of quickly and accurately creating an algorithm for extracting features from content data such as song data. A feature extraction algorithm creation apparatus 20 includes: a low-level feature extraction expression list creation section 21 that creates as many as “n” low-level feature extraction expression lists each constituted by “m” low-level feature extraction expressions; a low-level feature computation section 24 that substitutes input data of “j” songs into “n” low-level feature extraction expression lists so as to acquire “n” combinations of “m” low-level features corresponding to each input data item; and a high-level feature extraction expression learning section 25 that estimates high-level feature extraction expressions through learning based on training data corresponding to “n” low-level feature outputs (“k” high-level features corresponding to each of “j” songs). This invention can be applied to systems for acquiring high-level features of songs and videos.
