In this article, we discuss the application of a combination of Neural Networks and Fuzzy Logic techniques to fundamentalist analysis of stock investment. Several researchers have used neural networks models in a variety of ways to predict short and long-term stock forecasting, but most of these models use technical indicators as inputs. This paper presents(More)
The main goal of the Artificial General Intelligence field (AGI) to create " human level intelligence " is known as a very ambitious one (Hut04). On the way to the field development there are many difficult problems to solve, like natural language translation, for example, which seem to share some " hardness " properties. The terms " AI-Complete " and "(More)
The purposes of this paper are: i) show how to use the previous knowledge of any economic analyst and represent this knowledge using frames [7]; ii) discuss the application of a combination of Neural Networks and Fuzzy Logic to predict the evolution of stock prices of Brazilian companies traded on the São Paulo Stock Exchange; iii) present the obtained(More)
