The Physical Limits of Communication
Lachmann, Michael; Newman, M. E. J.; Moore, Cristopher - Santa Fe Institute - 1999
It has been well-known since the pioneering work of Claude Shannon in the 1940s that a message transmitted with optimal efficiency over a channel of limited bandwidth is indistinguishable from random noise to a receiver who is unfamiliar with the language in which the message is written. In this...

Analysis of Correlations Between Sites in Models of Protein Sequences
Giraud, B. G.; Lapedes, Alan; Liu, Lon Chang - Santa Fe Institute - 1998
A criterion based on conditional probabilities, related to the concept of algorithmic distance, is used to detect correlated mutations at noncontiguous sites on sequences. We apply this criterion to the problem of analyzing correlations between sites in protein sequences, however, the analysis...

Discovering Noncritical Organization: Statistical Mechanical, Information Theoretical, and Computational Views of Patterns in One-Dimensional Spin Systems
Feldman, David P.; Crutchfield, James P. - Santa Fe Institute - 1998
measures of pattern from information theory and computational mechanics differ from known thermodynamic and statistical … mutual information called the excess entropy---an information theoretic measure of memory---serves to detect ordered, low … entropy density patterns. It is superior in many respects to other functions used to probe the structure of a configuration …

Computational Mechanics: Pattern and Prediction, Structure and Simplicity
Shalizi, Cosma Rohilla; Crutchfield, James P. - Santa Fe Institute - 1999
Computational mechanics, an approach to structural complexity, defines a process's causal states and gives a procedure for finding them. We show that the causal-state representation--an e-machine--is the minimal one consistent with accurate prediction. We establish several results on e-machine...

Self-Organization of Spatial Infrastructure
Yegorov, Yuri - Santa Fe Institute - 1997
The paper discusses the role of self-organizing phenomena like emergence of infrastructure and self-organizing criticality in a spatial economy. Some theoretical models are discussed and reviewed. Computer models in the form of simple cellular automata, similar to the game "Life" and Schelling's...
