ANN - Classification Print E-mail
< Prev   Next >
This module uses neural network model to classify non-numerical (categorial, or factor) response Z based on one or more numerical predictors X. The response has usually text values, like “PETER”, “JOHN”, etc. called “levels”. The levels have no order (one cannot say whether one level is greater than another). The factor must have at least two levels, for example: (A, B, C, D, E); (YES, NO); (green, blue, yellow); (“Elytrigia repens”, “Lolium perenne”, “Phleum pratense”), etc. If there are numbers in the factor columns, they are interpreted as text with no numerical value. The goal of the classification module is to find any possibly existing relationship between the predictors and the response. Examples of applications is industrial fault identification, diagnosis support from a blood analysis, and many applications in psychology, chemical and environmental research, biology and life sciences, assessing and predicting activity of drugs in pharmaceuticals, and so on. .
