information theory

n.
The theory of the probability of transmission of messages with specified accuracy when the bits of information constituting the messages are subject, with certain probabilities, to transmission failure, distortion, and accidental additions.

information theory

n
(Mathematics) a collection of mathematical theories, based on statistics, concerned with methods of coding, transmitting, storing, retrieving, and decoding information

To investigate the relationships between Ringed Salamander occupancy and environmental variables, we used an information-theoretic approach to model selection (Burnham and Anderson, 2002).
The Experience of Human Communication: Body, Flesh, and Relationship begins with an introductory chapter, wherein Macke describes the current state of communication studies, as an information-theoretic discourse situated among the natural sciences, and where he would like to see the thinking around it shift, to a more experiential, fluid activity that cannot be so scientifically defined.
The main objectives of the project are to elaborate and investigate the concept of socSMCs in terms of information-theoretic and neurocomputational models, to deploy them in the control of humanoid robots (PR2, REEM-C) for social entrainment with humans, to elucidate the mechanisms for sustaining and exercising socSMCs in the human brain, to study their breakdown in patients with autism spectrum disorders, and to benchmark the socSMCs approach in several demonstrator scenarios.

This work builds on early theoretical contributions that identified two broad sources of media bias: supply-side factors, such as the objectives of governments, (4) owners (5), and journalists (6), and demand-side factors, such as voters' preferences for confirmatory information (7) and information-theoretic motives for coarsening information (8).
