Abstract
SO] pollution of the atmosphere is one of the problems that have not
yet been solved in Slovenia, especially around large coal fired thermal
power plants. In past years we have developed Perceptron neural network
based models for short - term forecasting of ambient SO] concentrations.
Basically the forecasting model is taught with patterns that
represent SO] concentrations and the meteorological history of the
observed polluted site. Therefore it is very important how these patterns
are selected in order to obtain a model that is capable of accurate
forecasting for as many different pollution situations as possible.
Three types of pattern selection strategies were developed. The
models built according to these pattern selection strategies were tested
