Dr. Vinizki of the Moscow National Research Center for Surgery reviews PolyAnalyst

A number of clinics around the world perform heart transplantation. One of the most difficult problems in this field is rejection of the transplanted tissue. It is critically important to know the degree of this rejection. Today the most accurate method to measure it is biopsy (analysis of a small piece of tissue taken from the patient). However, making a biopsy of the heart tissue is a complex, dangerous, and…

Regression-based classification methods and their comparison with decision tree algorithms

Classification learning can be considered as a regression problem with dependent variable consisting of 0s and 1s. Reducing classification to the problem of finding numerical dependencies we gain an opportunity to utilize powerful regression methods implemented in the PolyAnalyst data mining system. Resulting regression functions can be considered as fuzzy membership indicators for a recognized class. In order to obtain classifying rules, the optimum threshold values which minimize the number…

PolyAnalyst data analysis technique and its specialization for processing data organized as a set of attribute values

Abstract: The data analysis techniques of the PolyAnalyst data mining system are based on the automated synthesis of functional programs treated as the multi-dimensional non-linear regression models. This approach provides the system with two valuable properties: 1) it can discover in data the hidden relations that might be of a great variety of forms, 2) it can explore arbitrarily complexly structured data if the corresponding data access primitives are provided.…

Megaputer releases its new data mining product PolyAnalyst v2.01

PolyAnalyst is a convenient integrated environment for database exploration. It has a friendly object-oriented user interface. PolyAnalyst incorporates a set of powerful tools – exploration engines for intelligent data analysis. The main engine, Core PolyAnalyst, finds exact form of multi-parameter functional dependencies in data, expressing them as mathematical formulae and/or structural algorithms including IF and FOR blocks, as well as other constructions. A unique feature of PolyAnalyst is its ability to…
