SEVERAL COMPANIES offer relatively low-cost neural-network simulation software that runs on PCs. These simulators can solve real problems such as diagnosing circuit-board failures or predicting financial trends in futures markets. The simulators are simple and straightforward to use for anyone familiar with PC software. But designing a network model and gathering good data to train a neural network can require all the skill and creativity you've developed as an engineer.

Neural networks excel at recognizing patterns in data. The most publicized applications of the networks include analysis of consumer loan applications and image and character recognition. You train neural networks with known data rather than using a programming algorithm that has a...
