摘要： A feature calculation unit 81 calculates a feature that is likely to influence cancellation by a user based on a communication state log that indicates a communication state of a base station when the user has been engaged in communication or making a call. A learning device 82 learns a model representing a behavioral characteristic of the user by using the calculated feature as an explanatory variable. A prediction device 83 predicts the behavioral characteristic of the user using the feature generated from the communication state log and the model.

摘要： A region linear model optimization system optimizes a region linear model, and includes: a linear model setting unit 81 for setting for a partition a linear model to be applied to one of regions representing subspaces divided by the partition, the partition being an indicator function dividing an input space into two portions; and a region model calculation unit 82 for representing a model of each of the regions in the region linear model as a linear combination of the linear models to be applied to the respective regions.

摘要： A prediction data input unit 91 inputs prediction data that is one or more explanatory variables that are information likely to affect future sales. An exposure pattern generation unit 92 generates an exposure pattern which is an explanatory variable indicating the content of a commercial message scheduled to be performed during a period from predicted time to future prediction target time. A component determination unit 93 determines the component used for predicting the sales, on the basis of a hierarchical latent structure that is a structure in which latent variables are represented by a tree structure and components representing probability models are located at nodes of a lowest level of the tree structure, gating functions for determining a branch direction in the nodes of the hierarchical latent structure, and the prediction data and the exposure pattern. A sales prediction unit 94 predicts the sales on the basis of the component determined by the component determination unit 93 and of the prediction data and the exposure pattern.

摘要： A diagnostic device detects a fault and estimates its cause based on the degree of change of a plurality of attributes of data measured from an object being diagnosed. A diagnostic object change degree pattern generation unit 110 calculates the degree of change of each attribute of data, including a plurality of attributes of the object being diagnosed measured from the object being diagnosed to generate a diagnostic object change degree pattern which is a combination of values of the degree of change of the respective attributes. A criterion change degree pattern memory 150 holds in store a criterion change degree pattern, formed of a pattern of values of the degree of change of the attributes of data measured from the object being diagnosed, in association with event(s)-to-be-diagnosed on the fault sort basis or on the fault cause basis. A change degree pattern diagnosis means 120 effects pattern matching between the diagnostic object change degree pattern and the criterion change degree pattern in the criterion change degree pattern memory to diagnose the object being diagnosed.
