CS 416 Artificial Intelligence. Lecture 24 Neural Networks Chapter 20. Neural Networks. Read Section 20.5 Small program and homework assignment. Model of Neurons. Multiple inputs/dendrites (~10,000!!!) Cell body/soma performs computation Single output/axon
The sum of the inner product of the input and weights is calculated
If this sum exceeds a threshold, the perceptron firesPerceptrons
What do these weights mean?
In general, how often should we reprocess?Perceptron Example

“I hate math... so little room to make small errors.” – Caleb Schaefer, UGA student
Why are we ignoring the other weight changes?
