Title:
情報処理装置、プログラム及び情報処理方法
Document Type and Number:
Japanese Patent JP7408025
Kind Code:
B2
Abstract:
An information processing device 100 is provided with: a storage unit (102) that stores a log-likelihood matrix indicating log-likelihoods as components of a matrix in which unit series lengths and time steps are arranged in ascending order; a matrix rotation operation unit (103) that generates a shifted log-likelihood matrix by performing a shifting process for shifting log-likelihoods, for which the length and the time step are incremented by one unit, such that the log-likelihoods are aligned on a line in ascending order according to the length; a continuous generation probability parallel calculation unit (104) that generates a continuous generation probability matrix by adding, in the shifted log-likelihood matrix, log-likelihoods of each line from the leading component to each subsequent component of the line; a matrix rotation operation unit (103) that generates a shifted continuous generation probability matrix by shifting continuous generation probabilities in the continuous generation probability matrix such that the destination and the source of each component, the value of which has been shifted by the shifting process, are reversed; and a forward probability sequential parallel calculation unit (105) that calculates forward probabilities using the shifted continuous generation probability matrix.
