Outline What is a Neural Network? How does it work? Why do we care? Results Issues encountered Future work
Neural Network Input Layers Output Layers Hidden Layers
Idea of Learning Not realistic to study every possible case Smaller sample can be used to model the entire case Assume connections hold
Learning Methods (input)=[age, income, credit score, etc] (output)=[dependability] We want weights of α’s X*α(Hidden)=Y
Learning Methods-Cont. Use the learning method to find α I Y-Xα I=0
Data Testing Random Data can’t be learned Deterministic Data can be learned Adding Random variance decreases Accuracy More values of N the Better But more values of N take Longer
Future Work Increase the speed of the Neural Network Find more applicable data for testing of the Neural Network Try multiple layer Neural Networks and Compare
