1 Neural Networks Chris Hall Marius Francu

2 An Artificial Neural Network (ANN) is an information processing paradigm that is inspired by the way biological nervous systems process information. Composed of a large number of highly interconnected processing elements that work in unison to solve specific problems. What are neural Networks?

3 Derive meaning from complicated or imprecise data Adaptive learning. Fault Tolerance Why do we use neural networks?

4 Biological Vs. Artificial Neurons Electoral – chemical communication Refraction period Physical length Nodes of Ranvier Myelin sheath Electrical communication No Refraction period Fire rate No “Physical” length No need for Nodes of Ranvier

5 Biological Vs. Artificial Cont.
