Patent ID: 7881524

Claim:
An information processing apparatus, the apparatus comprising: a plurality of sensing means for sensing a plurality of types of data from a space in which a person exists; detection means for detecting a plurality of kinds of feature amounts from the plurality of types of data sensed by said plurality of sensing means; calculation means for calculating respective valid values of the plurality of kinds of feature amounts detected by said detection means; selection means for selecting at least one feature which has a relatively high valid value from among the plurality of kinds of feature amounts, on the basis of the respective valid values calculated by said calculation means; and identification means for identifying the person by using at least the selected one feature amount with the relatively high valid value, wherein said calculation means includes: means for performing processing for obtaining normalized output level Vi of modules for detecting the feature amounts with respect to all classes i in a final layer of a hierarchical neural network; means for calculating a sum total S=V 1 +V 2 +, . . . V N of output levels in all the classes; and means for calculating a valid value Yi of the feature amount in class i by computing Yi=ki×Vi/S where ki represents the appearance frequency in class i.
