WebBinary threshold neurons • McCulloch-Pitts (1943): influenced Von Neumann. – First compute a weighted sum of the inputs. – Then send out a fixed size spike of activity if the weighted sum exceeds a threshold. WebA threshold logic neuron employs a single inner product based linear discriminant function y : Rn+1 → R, y(X) = XTW where X,W ˜ Rn+1 and the bias or threshold value w 0, is included into the weight vector. The hyperplane decision surface y(X) = 0 divides the space into two regions, one of which the TLN assigns to class C fnf infected
