Motivation• Artificial neural networks(ANNs) are applied
to a wide range of forecasting problems.
• However, using ANNs to model linear problems
have yielded mixed results, and hence; it’s not wise
to apply ANNs blindly to any type of data.
Intelligent Database Systems Lab
Objectives• To overcome limitation of ANNs and yield more
general and more accurate forecasting model.
Intelligent Database Systems Lab
Conclusions
• A novel hybridization of ANNs and ARIMA model is
proposed in order to overcome the limitation of ANNs
and yield the more general and the more accurate
forecasting model.
