LECTURES #22&23: METANEURAL HANDS-ON
About 80 percent of artificial neural network applications are based on the backpropagation
algorithm. This lecture will review backpropagation (history and algorithm) and illustrates the
use of the MetaNeural software to solve some practical neural network problems. We will
discuss a fully connected feedforward (perceptron) type of neural network trained with the
backpropagation algorithm. Neural network applications addressed in the literature range from
pattern recognition, classification, clustering, visualization, (process) control and neuro-control,
game playing, diagnostics (e.g., car industry, medical, manufacturing), forecasting, prediction,
regression models, optimization (e.g. finance), hardware and embedded control implementation,
code simulation, and in-silico drug design. Practical implementations of neural networks will
discuss the bias, the number of hidden layers, the number of neurons, transfer functions,
preprocessing, training parameters, momentum, data preparation and preprocessing, other cost
functions, training strategies, pruning and growing of networks, when to stop training, the curse
of dimensionality, bootstrapping, …

Homework #4 (due April 19)
Experiment with the iris data and Analyze and show your predictions for iris.tes. The homework
should be in a report style and rich on graphics. The purpose of the homework is to show that you
are competent applying a neural network for making predictions on a dataset. You can
additionally run other datasets or use different neural network software.
