We propose a method for botnet detection from darknet data by non-negative matrix factorization (NMF), which can decompose the vector valued time series data into several components. In addition, we propose a new method to estimate the number of components in the data, by the minimum description length (MDL) principle. Our method for botnet detection consists of change point detection and analysis based on variance of the decomposed data.
