Chases and Escapes, and Optimization Problems
Toru Ohira
We propose a new approach for solving combinatorial optimization problem by utilizing the mechanism of chases and escapes, which has a long history in mathematics. In addition to t…
Delayed Random Walks and Control
Tadaaki Hosaka, Toru Ohira
Issues of resonance that appear in non-standard random walk models are discussed. The first walk is called repulsive delayed random walk, which is described in the context of a sti…
Balancing with Noise and Delay
Tadaaki Hosaka, Toru Ohira, Christian Luciani +2
Motivated by recent studies in human balance control, we study a delayed random walk with an unstable fixed point. It is observed that the random walker moves away from the unstabl…
Statistical Mechanical Approach to Lossy Data Compression:Theory and Practice
Tadaaki Hosaka, Yoshiyuki Kabashima
The encoder and decoder for lossy data compression of binary memoryless sources are developed on the basis of a specific-type nonmonotonic perceptron. Statistical mechanical analys…
Statistical Mechanical Approach to Error Exponents of Lossy Data Compression
Tadaaki Hosaka, Yoshiyuki Kabashima
We present herein a scheme by which to accurately evaluate the error exponents of a lossy data compression problem, which characterize average probabilities over a code ensemble of…
Statistical mechanics of lossy data compression using a non-monotonic perceptron
T. Hosaka, Y. Kabashima, H. Nishimori
The performance of a lossy data compression scheme for uniformly biased Boolean messages is investigated via methods of statistical mechanics. Inspired by a formal similarity to th…
