nofootnotes date March 2008 onesource date March 2008 Terminology Algorithmic learning theory is a mathematical framework for analyzing machine learning problems and algorithms. Synonyms include formal learning theory and algorithmic inductive inference . Algorithmic learning theory is different from statistical learning theory in that it does not make use of statistical assumptions and analysis. Both algorithmic and statistical learning theory are concerned with machine learning and can thus be viewed as branches of computational learning theory . Distinguishing Characteristics Unlike statistical learning theory and most statistical theory in general, algorithmic learning theory does not assume that data are random samples, that is, that data points are independent of each other. This makes the theory suitable for domains where observations are relatively noise free but not random, such as language learning ref Jain, S. et al 1999 Systems That Learn , 2nd ed.

The pragmatic theory of information PTOI is a set of concepts and principles for defining, measuring, and tracking the time evolution of information. PTOI is derived from Charles Sanders Peirce s general theory of semeiotic signs and inquiry . Peirce explored a number of ideas about information throughout his career. One set of ideas is about the laws of information having to do with the logic of information logical properties of information . Another set of ideas about time and thought have to do with the dynamics of inquiry dynamic properties of inquiry . All of these ideas contribute to the pragmatic theory of inquiry. Peirce set forth many of these ideas very early in his career, periodically returning to them on scattered occasions until the end, and they appear to be implicit in much of his later work on the logic of science and the theory of signs, but he never developed their implications to the fullest extent. More recently, Edward D. Weinberger formulated a quantitative theory of pragmatic information. In contrast to standard informationtheory that says nothing about the semantic content of information, Weinberger s theory attempts to measure the amount of information actually used in making a decision. Included in Weinberger s paper is a demonstration that his version of pragmatic information increases over the course of time in a simple model of evolution known as the quasispecies model . This is demonstrably not true for the standard measure of information. References Edward D. Weinberger Weinberger, Edward D. 2002 , A Theory of Pragmatic Information and Its Application ...

Anderson to describe and model how a person integrates information from a number of sources in to make an overall judgment. The theory proposes three functions. The valuation function V S is an empirically derived mapping of stimuli to an interval scale. It is unique up to an interval transformation y ax b .

Cognitive algebra refers to the class of functions that are used to model the integration process. They may be adding, averaging, weighted averaging, multiplying, etc. The response production function R M r is the process by which the internal impression is translated into an overt response. Information integration theory differs from other theories in that it is not erected on a consistency principle such as balance or congruity but rather relies on algebraic models.

In game theory , an information set is a set that, for a particular player, establishes all the possible moves that could have taken place in the game so far, given what that player has observed. If the game has perfect information , every information set contains only one member, namely the point actually reached at that stage of the game. Otherwise, it is the case that some players cannot be sure exactly what has taken place so far in the game and what their position is. More specifically, in the extensive form game extensive form , an information set is a set of decision nodes such that Every node in the set belongs to one player. When play reaches the information set, the player with the move cannot differentiate between nodes within the information set, i.e. if the information set contains more than one node, the player to whom that set belongs does not know which node in the set has been reached. The notion of information set was introduced by John von Neuman motivated by studying the game of Poker .

Redundancy in informationtheory is the number of bits used to transmit a message minus the number of bits of actual information in the message. Informally, it is the amount of wasted space used to transmit certain data. Data compression is a way to reduce or eliminate unwanted redundancy, while checksum s are a way of adding desired redundancy for purposes of error detection when communicating over a noisy channel of limited channel capacity capacity . Quantitative definition In describing the redundancy of raw data, recall that the Entropy rate rate of a source of information is the average Information entropy entropy per symbol. For memoryless sources, this is merely the entropy of each symbol, while, in the most general case of a stochastic process, it is math r lim n to infty frac 1 n H M 1, M 2, dots M n , math the limit, as n goes to infinity, of the joint entropy of the first n symbols divided by n . It is common in informationtheory to speak of the rate or Information entropy entropy of a language. This is appropriate, for example, when the source of information is English prose. The rate of a memory less source is simply math H M math , since by definition there is no interdependence of the successive messages of a memory less source. The absolute rate of a language or source ... Aspects, p. 248 262, Springer 2010.
