Plot perceptron input/target vectors
Syntax
plotpv(P,T
)
Description
plotpv(P,T)
take these inputs,
P - R x Q
matrix of input vectors (R
must be 3 or less).
T - S
x Q
matrix of binary target vectors (S
must be 3 or less).
and plots column vectors in P
with markers based on T
.
plotpv(P,T,V)
takes an additional input,
V -
Graph limits = [x_min x_max y_min y_max]
and plots the column vectors with limits set by V
.
Examples
The code below defines and plots the inputs and targets for a perceptron:
p = [0 0 1 1; 0 1 0 1]; t = [0 0 0 1]; plotpv(p,t)
The following code creates a perceptron with inputs ranging over the values in P
, assigns values to its weights and biases, and plots the resulting classification line.
net = newp(minmax(p),1); net.iw{1,1} = [-1.2 -0.5]; net.b{1} = 1; plotpc(net.iw{1,1},net.b{1})
