Michael Holden Faculty Sponsor: Professor Gordon H. Dash
2
ANN is structured after a biological neural network A mathematical model that attempts to mine, predict, and forecast data Provides Artificial Intelligence (AI)
3
A process of pattern recognition and manipulation is based on: ◦ Massive Parallelism ◦ Connectionism ◦ Associative Distributed Memory
4
Brain contains an interconnected net of approximately 10 billion neurons (cortical cells) Biological Neuron The simple “arithmetic computing” element
5
Mathematical Model of human- brain principles of computations Consists of elements called the biological neuron prototype ◦ Interconnected by direct links (connections) ◦ Cooperate to perform PDP to solve a computational task
6
New paradigms of computing mathematics consists of the combination of artificial neurons into artificial neural net ? Brain-Like Computer
7
Data Acquisition Data Analysis Interpretation and Decision Making Signals & parameters Characteristics & Estimations Rules & Knowledge Productions Data Acquisition Data Analysis Decision Making Knowledge Base Adaptive Machine Learning via Neural Network

Actual Return -Predicted Return Residual How well did it learn?
20
Small Residuals ◦ Most < 1bp Very Fit Model
22
2 Factors ◦ Global vs. Domestic Principal Component Analysis Explains Majority of Variance ◦ Some variance not captured by residuals
23
Fit Model ◦ Learned very well Small Residuals ◦ Trained very well Factors explained 90.4% of variance ◦ Include global and domestic independent variable next time Excellent Predictive Ability
