At present, many human activities are influenced by the use of information technologies, undergoing major changes to adapt to them. However, in the field of education, the changes that have occurred are not enough to break with the classical learning schemes and there are lot of voices that are demanding radical changes in this context. Mainly one of the fundamental characteristics that educators...
Portfolio is a document describing skills, experience, interest or knowledge of a person. Currently, the conventional portfolio paper-based is no longer able to keep pace with times. Therefore, some researchers suggest e-portfolios overcome this weakness. Previous studies have attempted to create a model of ideal e-portfolios. This includes Shopping Trolley Model, Toast Rack Model, Spinal Column Model,...
This paper presents the partial results obtained at the doctoral work titled ADAPTIVE HYBRID SYSTEM FOR THE VALUE AT RISK ESTIMATION ON PORTFOLIOS, where different AI techniques are used. This expert system tries to predict the portfolio variability with two o more assets, where the ROI and the risk rate are vital to define the efficient frontier market proposed by Markowitz.

How to allocate the weights of stocks is an interesting technology in stock index optimized replicate. This paper proposed a hybrid algorithm of adaptive genetic algorithm and pattern search (AGA-PS) to find the optimal portfolio weights. In AGA-PS, the crossover probability and mutation probability are adjusted adaptively. The weight from adaptive genetic algorithm is as the search start point of...
