NETWORK LEARNING DEVICE, NETWORK LEARNING SYSTEM, NETWORK LEARNING METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To stably learn a network without using a large amount of data with a teacher.SOLUTION: A network learning device includes: a first learning part for learning a first network for converting an input signal to a first signal; a second learning part for learning a second network for converting the first signal to a second signal; and a third learning part for learning a third network for converting the second signal to an output signal. The first learning part learns the first network as an encode part of a first auto encoder for encoding a training input signal to a first training signal and then decoding the signal to the training input signal. The second learning part learns the second network by back propagation with a second training signal corresponding to the first training signal as teacher data. The second training signal is generated by an encode part of the second auto encoder for encoding a third training signal to the second training signal and then decoding the signal to the third training signal.SELECTED DRAWING: Figure 2
