Research Abstract

We have developed the acoustic diagnosis system which is capable of adapting to the dynamic environment.
The major results of the project as follows :
1. Development diagnostic networks
We proposed a novel model of modular neural networks which has the ability to adapt its structure according to the environment. Experiments were performed for an artificial gas leakage device with various experimental conditions to imitate the change of environment for a long term. The discrimination accuracy with the proposed network was observed to be about 93%. Result shows that the proposed model is effective for detection of the leakage sound for the practical use.
2. Independent component analysis and evolutionary computation as feature extraction
We have examined the feature extraction for acoustic signal using independent component analysis and genetic algorithms to obtain the stable diagnosis. We proposed a novel recognition method using features extracted by ICA. The proposed method consists of some modules for each category and a synthesizer. We evaluate the performance of the proposed method for several recognition tasks including acoustic diagnosis. From these results, we confirmed the effectiveness of the recognition method using independent components for each class. The effectiveness of the proposed method were also confirmed for biological instruments.
