1.What is an artificial neural network and for what types of problems can it be used?
2.Compare artificial and biological neural networks. What aspects of biological networks are not mimicked by arti- ficial ones? What aspects are similar?
3.What are the most common ANN architectures? For what types of problems can they be used?
4.ANN can be used for both supervised and unsupervised learning. Explain how they learn in a supervised mode and in an unsupervised mode.
