Title:
DYNAMIC DISTRIBUTION ESTIMATION DEVICE, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/159845
Kind Code:
A1
Abstract:
An objective of the present invention is to enable estimation of parameters for a model including censored data rapidly and with efficient memory use such that parameters are temporally contiguous. A responsibility/responsibilities update part 19 updates responsibility/responsibilities on the basis of newly observed sample data. A moment update part 20 updates a moment on the basis of the newly observed sample data. A statistic update part 21 updates each statistic on the basis of either the responsibility/responsibilities or the moment. A parameter update part 22 updates a parameter relating to a component on the basis of each of the statistics.
