Sztuczne sieci neuronowe dla modeli zmienności
Języki publikacji
Abstrakty
W artykule przedstawiono pobieżnie ideę modeli typu ARCH, a także idę sztucznych sieci neuronowych. Modele rodziny ARCH umożliwiają wykorzystanie do prognozowania warunkowych momentów rzędu wyższego niż jeden. Sieci neuronowe zaś charakteryzują się dużymi możliwościami aproksymacji funkcji. Przedstawiono próbę zbudowania modelu łączącego zalety modeli ARCH i sieci neuronowych. (abstrakt oryginalny)
This paper presents an extension to backpropagation networks for financial time series prediction. We want the network that uses the information carried by the first and second order conditional moments of the distribution of interest, so as to combine its built-in nonlinear features with the typical dependence implied by ARCH-type and Stochastic Volatility models, whose effects must be estimated. A likelihood-type performance measure is discussed and learning schemes are suggested for conditionally Gaussian models. (original abstract)
