Title:
DATA PREDICTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/141344
Kind Code:
A1
Abstract:
This data prediction device is equipped with: a data observation means that observes the values of time-series data; a model identification means that uses a stochastic differential equation model to identify a steady-state model and a nonsteady-state model, on the basis of past observed time-series data; a likelihood calculation means that calculates likelihoods, which are values expressing the likelihood of the steady-state model and the nonsteady-state model; a mixing ratio calculation means that calculates the mixing ratio of the steady-state model and the nonsteady-state model on the basis of the respective likelihoods of the steady-state model and the nonsteady-state model; and a probability distribution prediction means that predicts the probability distribution of the time-series data on the basis of a prediction model obtained by mixing the steady-state model and the nonsteady-state model according to the mixing ratio.
