— This paper describes a decision system based on rules for the management of a stock portfolio using a mechanism of dynamic learning to select the stocks to be incorporated. This system simulates the intelligent behavior of an investor, carrying out the buying and selling of stocks, such that during each day the best stocks will be selected to be(More)
This paper describes a decision system based on rules for the management of a stock portfolio using a fuzzy inference system to select the stocks to be incorporated. This system simulates the intelligent behavior of an investor, carrying out the buying and selling of stocks, such that during each day the best stocks will be selected to be incorporated in(More)
In the preprocessing step of a knowledge discovery process, the method of discretization selected can have a remarkable impact on the performance and accuracy of classification algorithms. In this article, we analyze and compare expert discretization and automatic discretization algorithms. In particular, we study their impact to predict the survival of(More)
