Title:
LEARNING METHOD FOR LEARNING MACHINE
Document Type and Number:
Japanese Patent JP3238178
Kind Code:
B2
Abstract:

PURPOSE: To adjust to easy-to-converge and well-balanced output by adjusting a parameter so as to minimize the value of a loss function decreasing with the increase of the difference between an output vector and a bad example teacher within teacher signals.
CONSTITUTION: A loss function calculating means 8 is constituted of the loss function calculating means 9 by a model teacher and the loss function calculating means 10 by the bad example teacher. In this case, the bad example teacher within the teacher signals is defined as data not to be outputted as the output vector, therefore, to be avoided. Then, by the difference (x) between the bad example teacher and the output vector, the loss function (r) for decreasing along with the increase of the difference (x) is calculated with an equation (r)=exp(-x2). Then, when the value of the loss function is larger than a prescribed value, a control parameter is updated so as to reduce the value of the loss function until the value of the loss function becomes smaller than the prescribed value, the loss function is repeatedly calculated and when the calculated loss function reaches the value smaller than the prescribed value, the latest updated control parameter is integrated into the learning machine.
