Michael Holden Faculty Sponsor: Professor Gordon H. Dash ANN is structured after a biological neural network A mathematical model that attempts to mine, predict, and forecast data Provides Artificial Intelligence (AI) A process of pattern recognition and manipulation is based on: ◦ Massive Parallelism ◦ Connectionism ◦ Associative Distributed Memory Brain contains an interconnected net of approximately 10 billion neurons (cortical cells) Biological Neuron The simple “arithmetic computing” element Mathematical Model of humanbrain 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 New paradigms of computing mathematics consists of the combination of artificial neurons into artificial neural net Brain-Like Computer ?
