Abstract(in English) In this paper, we propose anomaly detection in hammering echoes using a domain-adapted deep neural network for an unknown environment. In this method, in order to acquire essential feature expression contributing to discrimination between normality and anomaly, while constructing a label classifier for hammering echoes acquired in the source domain, it trains a domain classifier so that it can not distinguish domains at the same time. This makes it possible to realize high precision discrimination without the training labels in the adaptation target domain. In order to verify the effectiveness, we evaluate the proposed method by using hammering echoes obtained from three different test concrete blocks. As a result, our proposed method improved the recognition rate by about 27% on average as compared to the conventional method.
