New algorithms for computing the correct decoding probability exponent for lossy source coding
Yutaka Jitsumatsu (Tokyo Tech.), Yasutada Oohama (UEC) IT2022-17
Abstract (in Japanese) (See Japanese page) 
(in English) In a 1976 paper, Arimoto proposed an algorithm for computing the error exponent and the correct decoding probability exponent of channel coding.
In this paper, Arimoto also proposed an algorithm to compute the error exponent and the correct decoding probability exponent of channel coding under a cost constraint and an algorithm to compute the error exponent of source coding that allows distortion.
The authors proposed an algorithm to compute the correct decoding probability exponent of lossy source coding in 2016.
This algorithm is based on Csisz'ar and K"orner's expression of the correct decoding probability exponent.
In this paper, we propose still a new algorithm to compute the correct decoding probability exponent of lossy source coding.
The difference between Arimoto's algorithm for computing the error exponent, the authors' previous algorithm
and the new algorithm of this paper is clarified.
