A problem of classification by precedents in partial precedence models is considered. An algorithm is presented for searching for maximum logical regularities of a class (LRCs) for consistent training tables. A two-level solution scheme of a problem is proposed for finding an optimal decision rule. First, LRCs are obtained by training data, and a mapping of(More)
Questions of use of pattern recognition methods in medical tasks are discussed. The Recognition program system is presented, which contains a variety of pattern recognition and cluster analysis methods. Some methods based on voting by a system of regularities are discussed in more detail. An example of solved tasks of hysteromyoma relapse forecasting is(More)
A system for computer-assisted design of inorganic compounds, with an integrated complex of databases for the properties of inorganic substances and materials, a subsystem for the analysis of data, based on computer training, a knowledge base, a predictions base, and a managing subsystem, has been developed. The methodology of integration of software(More)
Methods for the analysis of medical data and the results of their application to the treatment of a number of socially important diseases in important medical areas (cardiology, neurology, surgery, and oncology) are considered. The precedent approach is investigated. Practical methods of discrete analysis of training data, logical and statistical methods(More)
An approach of solving the problem of multiclass supervised classification, based on using errorcorrecting codes is considered. The main problem here is the creation of binary code matrix, which provides high classification accuracy. Binary classifiers must be distinct and accurate. In this issue, there are many questions. What should be the elements of the(More)
The possibility of searching for classification regularities in large arrays of chemical information with the use precedent-based recognition methods is discussed. The results of application of these regularities to the computer-assisted design of inorganic compounds promising for the search for new materials for electronics are presented.
Calibration of the digital projector is a necessary procedure for many 3D scanners. The proposed method for automatic calibration of a projector uses binary color templates and searches for the most stable points for minimization of decoding errors. The camera resolution must significantly exceed the projector’s resolution. The method can be easily adapted(More)
