This paper intends to propose an integrated method which combines selforganizing map (SOM) network with genetic algorithm (GA) and particle swarm optimization (PSO)-based (ISGP) algorithm to train the radial basis function (RBF) network for function approximation. The experimental results for three benchmark problems indicated that such integration can have better performance. In addition, usin...

Crop decision planning is an important part of effective farm management. Because of the many uncertain factors such as weather variations, technology advances, and crop yields and prices, all of which prove to change considerably, decision planning can be very complex. The focus of this paper is to develop accurate yield and price forecasting models to aid in decision planning. For yield forec...

The paper presents a theory of nominal asset prices for competitively owned oil. Focusing on monetary e¤ects, with ‡exible oil prices the US dollar oil price should follow the aggregate US price level. But with rigid nominal oil prices, the nominal oil price jumps proportionally to nominal interest rate increases. We …nd evidence for structural breaks in the nominal oil price that are used to i...

The day-ahead electricity market is closely related to other commodity markets such as the fuel and emission markets and is increasingly playing a significant role in human life. Thus, in the electricity markets, accurate electricity price forecasting plays significant role for power producers and consumers. Although many studies developing and proposing highly accurate forecasting models exist...
