Kraft - Chaitin Inequality
Kraft’s inequality [9] is essential for the classical theory of noiseless coding [1, 8]. In algorithmic information theory [5, 7, 2] one needs an extension of Kraft’s condition from finite sets to (infinite) recursively enumerable sets. This extension, known as Kraft-Chaitin Theorem, was obtained by Chaitin in his seminal paper [4] (see also, [3, 2], [10]). The aim of this note is to offer a si...

Kraft's inequality [9] is essential for the classical theory of noiseless coding [1, 8]. In algorithmic information theory [5, 7, 2] one needs an extension of Kraft's condition from nite sets to (in nite) recursively enumerable sets. This extension, known as Kraft-Chaitin Theorem, was obtained by Chaitin in his seminal paper [4] (see also, [3, 2]). The aim of this note is to o er a simpler proo...
متن کاملKraft: An Agent Architecture for Knowledge Fusion
Knowledge fusion refers to the process of locating and extracting knowledge from multiple, heterogeneous on-line sources, and transforming it so that the union of the knowledge can be applied in problem-solving. The KRAFT project has defined a generic agent-based architecture to support fusion of knowledge in the form of constraints expressed against an object data model. KRAFT employs three ki...
متن کاملLecture 7 : Prefix codes , Kraft - McMillian Inequality
In the previous lecture, we showed that Shannon constructed a code, which was a one-to-one mapping, that took a stream of data X = (X1, ..., Xn) generated iid from a distribution P (X) over a finite alphabet A = (a1, ..., aA) of size A, and compressed it using ≈ nH(X) bits in total or ≈ H(X) bits per symbol, on average (for sufficiently large n). The code was based considering a special subset ...
متن کاملResolving Ontological Heterogeneity in the KRAFT Project
KRAFT is an agent architecture for the integration of heterogeneous information systems. The focus in KRAFT is on the integration of knowledge in the form of constraints. In this article we describe the architecture from an ontological perspective. We start by introducing the agent architecture and illustrate its application in the telecommunication-network design. We then describe how we asses...
