Abstract(in English) | In recent years, Anomaly Detection is noticed in order to prevent a risk, perform security system and analyze behaviors. It is common to define the anomaly values using the probabilistic distribution estimation wherein the latent variable is assumed in Anomaly Detection. However, the data we can obtain in business are often heterogeneous and deficient. If the exiting methods are applied to heterogeneous and deficient data, it is difficult to analyze these data accurately and make a decision because the latent variable models result in complicated. In this paper, we propose the method that can detect explicit structural changes from high dimensional data of time series with the aim of detecting changes without assuming the latent variables. |
