Abstract(in English) | Usages of autoencoders (AEs) are not only a dimension reducer, but a generative model using reconstruction. AEs are used as the generative model in this work and applied to an abnormal detection. In usual abnormal detectors without label data, they require normal value to generate a model which generate normal values. By contrast, our AE as abnormal detector requires both of normal and abnormal data to generate a model. Proposed AE reconstructs a normal input regularly and an abnormal input irregularly, respectively. By proposed methods, reconstruction errors by abnormal input come to increase and it is easy to detect as abnormal input. This paper reports experiments about an abnormal detection with MNIST dataset by proposed AE. |
