Wiki MarkupPerceptron is a rule-weighting algorithm based on artificial neural networks ("perceptrons") instead of \["GeneticAlgorithm"\]s. It may replace the GA in the [RescoringProcess], or maybe it already has. Really, I'm creating this page because I don't really know how the perceptron algorithm fits into the rest of [SpamAssassin] and I'm hoping that someone who does will fill in the details.s. It is based on error back propagation by gradient descent and includes several security and accuracy-related modifications. It has replaced the GA in the RescoringProcess for SpamAssassin 3.0.
