neural networks in finance gaining predictive edge in the market [mcnelis p d ]

... that this predictive edge from neural networks will always lead to opportuni- ties for profitable trading [see Qi (1999 )], but any predictive edge certainly enhances the chance of finding such opportunities. This ... one perspective, the in uence is unidirectional, proceeding from diagnostic and forecasting methods to business and financial decision mak- ing. Diagnostics and...

... for predicting proper strain rate involved three phases First, data collection phase involved gathering the data for use in training and testing the neural network. A large training data reduces ... higher strain rates than those typically encountered in the field. These strain rates determine the pore pressures that will be generated in the testing and thus the appl...
