Computer investigations of sound perception and noise annoyance

Ossowski A., Smyrnova Y.

Journal of Medical Informatics & Technologies

2001

Vol. 2, Part. 2

SN27--SN32

The problem of influence of adverse sound environments on human psychophysical state and health has been outlined. Basic sound characteristics have been defined and the fundamental question of the relation between subjective and objective characteristics has been formulated. The general conception of a computer system for studying human perception of environmental sound and noise has been described. The usefulness of application of data mining algorithms in order to find practical rules that enable to determine subjective sound and noise parameters from the knowledge of physical ones has been pointed out.

A formal approach to rules interpretation working in medical databases

Ossowski A.

Journal of Medical Informatics & Technologies

2001

Vol. 2, Part. 1

MI139--MI145

Finite collections of data analysed by using statistical and/or data mining techniques are usually discrete representations of a continuous reality. Therefore the fundamental question arise whether rules and regularities discovered in data bases are fictive or describe essential properties of the real world. In order to answer this question a more general “continuous” insight into the problem of data representation, acquisition and analysis is necessary. A formal philosophical/mathematical approach to rules in data bases has been presented in this work. Ontological and epistemological ideas have been described in terms of differential geometry and topology. Various types of rules (geometric and non-geometric) in medical databases have been distinguished. The usefulness of the obtained results to the problem interpretation of medical data has been pointed out.
