Examples include disorders of consciousness Laureys ; Casali et al. Here, we address the phenomenon of structured experience from an information-theoretic perspective. Science strives to provide simple models that describe observable phenomena and produce testable predictions.
In line with this, we offer here the elements of a theory of consciousness based on algorithmic information theory AIT. AIT studies the relationship between computation, information, and algorithmic randomness Hutter , providing a definition for the information of individual objects data strings beyond statistics Shannon entropy.
Furthermore, we argue that brains, agents, and cognitive systems can be identified with special patterns embedded in mathematical structures enabling computation and compression. A brief summary of what we may call the Kolmogorov theory of consciousness KT is as follows.
Brains are model builders and compressors of information for survival. Cognition and phenomenal consciousness arise from modeling, compression, and data tracking using models. Then we shift to the objective view: what kind of mathematical structures connecting the concept of information with experience could describe the above? We argue that the proper framework is provided by AIT and the concept of algorithmic Kolmogorov complexity.
AIT brings together information theory Shannon and computation theory Turing in a unified way and provides a foundation for a powerful probabilistic inference framework Solomonoff.
These three elements, together with Darwinian mechanisms, are crucial to our theory, which places information-driven modeling in agents at its core.
To make the discussion more concrete, we briefly discuss Cellular Automata CA. Bayesian Reasoning and Machine Learning.

How to write a great review. The review must be at least 50 characters long. The result of each weighing is 0 if both pans are equal, -1 if the left pan is heavier, and 1 if the right pan is heavier.
Then the three weighings give the ternary expansion of the index of the odd coin. If the expansion is the same as the expansion in the matrix, it indicates that the coin is heavier.
If the expansion is of the opposite sign, the coin is lighter. Why does this scheme work? It is a single error correcting Hamming code for the ternary alphabet discussed in Section 8. Here are some details.
First note a few properties of the matrix above that was used for the scheme. All the columns are distinct and no two columns add to 0,0,0. Also if any coin 14 Entropy, Relative Entropy and Mutual Information is heavier, it will produce the sequence of weighings that matches its column in the matrix.
If it is lighter, it produces the negative of its column as a sequence of weighings. Combining all these facts, we can see that any single odd coin will produce a unique sequence of weighings, and that the coin can be determined from the sequence.
One of the questions that many of you had whether the bound derived in part a was actually achievable. For example, can one distinguish 13 coins in 3 weighings?
Elements of Information Theory
No, not with a scheme like the one above. Yes, under the assumptions under which the bound was derived.
The bound did not prohibit the division of coins into halves, neither did it disallow the existence of another coin known to be normal. Under both these conditions, it is possible to nd the odd coin of 13 coins in 3 weighings. You could try modifying the above scheme to these cases. Drawing with and without replacement. An urn contains r red, w white, and b black balls. Which has higher entropy, drawing k 2 balls from the urn with replacement or without replacement? Set it up and show why.Well-written, thorough, and accessible to anyone with a foundation in probability.
Markov Processes for Stochastic Modeling. In earlier work, we argued that the experience we call reality is a mental construct derived from information compression.
