Communication management device and communication management method

Abstract

The objective is to improve the accuracy of the generated anomalous traffic data. [Solution] The communication management device 1 includes a generator 131 that generates pseudo-data statistically similar to true data, using each of the series of communication volume observed for each time period corresponding to the second data as true data, and a discriminator 132 that identifies whether the pseudo-data generated by the generator 131 belongs to the class corresponding to true data or the class corresponding to pseudo-data. The device also includes a third learning unit 13 configured to learn multiple generative models, each having an objective function set with the probability distribution of the second data and the probability distribution of the first data determined from the ratio estimated by the first learning unit 11, and the second parameter estimated by the second learning unit 12.
