LIKELIHOOD ESTIMATION DEVICE, CONTENT DELIVERY SYSTEM, LIKELIHOOD ESTIMATION METHOD, AND LIKELIHOOD ESTIMATION PROGRAM

摘要

Provided is a likelihood estimation device, etc., for a data series expressed by a combination of a symbol and a transition time gap, wherein the transition time gap is taken into account. The likelihood estimation device (100) is provided with an input means (101) to receive input of the data series expressed by the combination of the symbol and the transition time gap; a storage means (104) to store a parameter (111) representing a specific statistical model of the data series; a likelihood calculation means (110) to calculate the likelihood for the statistical model of the data series using the parameter; and an output means (105) to output the likelihood calculated by the likelihood calculation means.
