An Algorithm for Computing the Stratonovich's Value of Information
Akira Kamatsuka, Takahiro Yoshida, Koki Kazama +1
We propose an algorithm for computing Stratonovich's value of information (VoI) that can be regarded as an analogue of the distortion-rate function. We construct an alternating opt…
A Generalization of the Stratonovich's Value of Information and Application to Privacy-Utility Trade-off
Akira Kamatsuka, Takahiro Yoshida, Toshiyasu Matsushima
The Stratonovich's value of information (VoI) is quantity that measure how much inferential gain is obtained from a perturbed sample under information leakage constraint. In this p…
A Stochastic Model for Block Segmentation of Images Based on the Quadtree and the Bayes Code for It
Yuta Nakahara, Toshiyasu Matsushima
In information theory, lossless compression of general data is based on an explicit assumption of a stochastic generative model on target data. However, in lossless image compressi…
An Efficient Bayes Coding Algorithm for the Non-Stationary Source in Which Context Tree Model Varies from Interval to Interval
Koshi Shimada, Shota Saito, Toshiyasu Matsushima
The context tree source is a source model in which the occurrence probability of symbols is determined from a finite past sequence, and is a broader class of sources that includes…
Evaluation of Error Probability of Classification Based on the Analysis of the Bayes Code: Extension and Example
Shota Saito, Toshiyasu Matsushima
Suppose that we have two training sequences generated by parametrized distributions and , where and are unknown true parameters. Given training seque…
Covariance Evolution for Spatially "Mt. Fuji" Coupled LDPC Codes
Yuta Nakahara, Toshiyasu Matsushima
A spatially "Mt. Fuji" coupled low-density parity check (LDPC) ensemble is a modified version of the original spatially coupled (SC) LDPC ensemble. Its desirable properties are fir…
