4.6 Hybrid Models
Normally, hybrid modeling techniques use physics-based process models, associ-
ated with any AI models to estimate processes which are uncertain or dif
cult to
model. In those approaches, some prior knowledge is incorporated into the black
box model, to reduce complexity and improve adaptation and prediction properties.
However, in this topic we are linking some data-based AI models with DWT. This
section describes basic details of hybrid neural models such as Neural Network
Autoregressive with Exogenous
Inputs
(NNARX), Adaptive Neuro-Fuzzy
