Pattern classifier device, pattern classifying method, computer program product, learning device, and learning method

摘要

According to an embodiment, a pattern classifier device includes a decision unit, an execution unit, a calculator, and a determination unit. The decision unit is configured to decide a subclass to which the input pattern is to belong, based on attribute information of the input pattern. The execution unit is configured to determine whether the input pattern belongs to a class that is divided into subclasses, using a weak classifier allocated to the decided subclass, and output a result of the determination and a reliability of the weak classifier. The calculator is configured to calculate an integrated value obtained by integrating an evaluation value based on the determination result and the reliability. The determination unit is configured to repeat the determination processing when a termination condition of the determination processing is not satisfied, and terminate the determination processing and output the integrated value when the termination condition, has been satisfied.

1. A pattern classifier device for determining whether an input pattern belongs to a class that is divided into a plurality of subclasses, the device comprising a processor that operates as:
a reception unit that receives the input pattern and attribute information of the input pattern; a decision unit that decides the subclass to which the input pattern is to belong, based on at least the attribute information; an execution unit that
determines whether the input pattern belongs to the class, using a weak classifier allocated to the decided subclass, andoutputs a result of the determination and a reliability of the weak classifier; a calculator that calculates an integrated value obtained by integrating an evaluation value based on the result of the determination and the reliability; and a determination unit that
determines whether a termination condition of determination processing performed by the decision unit, the execution unit, and the calculator, has been satisfied,repeats the determination processing when the termination condition has not been satisfied, andterminates the determination processing and output the integrated value at the time of the termination when the termination condition has been satisfied.
