    摘要： A method, system and computer program product for measured value simulation. The method including the steps of: observing measured values of an event to provide observed values, where the step of observing starts at a predetermined observation time; concurrently running a plurality of simulations, where the simulations have behaviors that are characterized by different parameters and start at the predetermined observation time; producing a discrete distribution at a predetermined timing after the predetermined observation time, where the discrete distribution are based on distances between the measured values provided by the predetermined timing and calculation of the simulations; and producing a second plurality of simulations based on the discrete distribution.

    摘要： A system, method, and computer program product allowing an information processing apparatus to function as a system for detecting an anomaly in an observation target on the basis of time series data. The system includes a first generation unit, a second generation unit, a singular vector computation unit, a matrix product computation unit, an element computation unit, an eigenvector computation unit and a change degree computation unit. The change degree computation unit computes the degree of change in the observation target from the reference periods to the target periods for anomaly detection, on the basis of a linear combination of the inner products between each of the eigenvectors and a singular vector, and then outputs the computed degree as a score indicating an anomaly in the observation target.

    摘要： Within aspects of the present invention, correlation anomalies are calculated in four stages for a reference data set, and a target data set, respectively, the four stages are: Initially, a similarity matrix K of the variables to be diagnosed is calculated. This similarity matrix is embedded in a low-dimensional vector space in order to calculate and obtain the coordinates {z1 . . . zp} for each variable. Next, an energy value {e1, . . . ep} is calculated per variable from calculated coordinates. Lastly, a comparison is made of the energy values that have been calculated for the target data set with the energy values of that have been calculated for the reference data set in order to determine the degree of correlation anomalies that has occurred between the two data sets.
