The paper deals with the problem of speaker-based segmentation. The goal of this task is to extract homogeneous segments containing the longest possible utterances produced by a single speaker. In the method presented here, no assumption is made about prior knowledge of the speaker or speech signal characteristics (there is no speaker model, no speech model, even the number of speakers in the r...

Structural studies are, in the social sciences, the indirect outcome of modern developments in mathematics which have given increasing importance to the qualitative point of view in contradistinction to the quantitative point of view of traditional mathematics. It has become possible, therefore, in fields such as mathematical logic, set theory, group theory, and topology, to develop a rigorous ...

In this issue of IEEE Systems, Man, and Cybernetics Magazine, four articles are presented that relate to the fascinating topic machine learning its application for real-world systems.

Search for an integrated, comprehensive theory of information science (IS) has so far been unsuccessful. Appearance of a theory has been retarded by one central constraint, the large number of disciplines concerned with human comnication. Crossdisciplinary interdependence occurs in two ways: theoretical relation of IS phenomena to a given science, and practical relation of the science to IS dis...

It is so common that it may be considered almost universal among second order cyberneticians, to identify second order cybernetics and radical constructivism, distinguished as opposite sides of the same coin. It is perhaps not so common that radical constructivists make this equation: they seem much more interested in the influence of radical constructivism in other subjects, especially educati...

In this essay communication is considered as a cybernetic system in which two participants (the representer and the representee) share a representation (made up of a representing and a represented), each constructing his own meaning from the identity of the representing and the represented in the representation in the form of a conversation. Meaning, in this context, is not seen as lying in any...

What is Bio-Cybernetics and Energy Medicine? Bio-cybernetics is a hot topic in the emerging field of energy medicine in Europe. Bio-cybernetic medicine is not a new idea but an old concept that has been given a new name. A bio-cybernetic matrix is a modern term for the acupuncture meridian system and the related medical field of acupuncture meridian assessment developed by Reinhold Voll, MD in ...

This paper provides an explanation of the increasing complexity of corporate IT management as a special case of application of the law of requisite variety. Frequently cited drawback of established frameworks of IT best practices like COBIT and ITIL is their complexity and related difficulty in their implementation. Through the perspective of the law of requisite variety, drawn from the field o...
