Machine Learning: Multi Layer Perceptrons
ml.informatik.uni-freiburg.deMulti layer perceptrons (cont.) multi layer perceptrons, more formally: A MLP is a finite directed acyclic graph. • nodes that are no target of any connection are called input neurons. A MLP that should be applied to input patterns of dimension nmust have n input neurons, one for each dimension.

hagan.okstate.eduPerceptron Architecture Before we present the perceptron learning rule, letÕs expand our investiga-tion of the perceptron network, which we began in Chapter 3. The general perceptron network is shown in Figure 4.1. The output of the network is given by. (4.2) (Note that in Chapter 3 we used the transfer function, instead of hardlim
