This comes from a combination of function approximation capabilities combined with statistical methods for parameter estim- ation and dynamical systems for modelling time variations. It is also true that the hype associated with some of the terminology in this area leads to many "blind" applications of neural networks to difficult problems. This talk is in two parts; firstly I will give an overview of some applications of neural networks in financial forecasting, focusing on sequential methods centered around the extended Kalman filtering framework. In the second part, I will talk about using neural net- works in an options pricing task. Sequential methods used in this framework will be extended to derive smooth estimates of implied volatilities from the Black-Scholes type approach. More recent work along the lines of replacing the extended Kalman filter by sequential sampling methods will also be discussed. Zeit: Donnerstag, 25.Juni 1998, 18:30 Uhr pktl.
