Unformatted text preview: Chapter 3 Perceptron Chapter 3 --- Perceptron 2 Perceptron c the simplest form of an ANN, used for the classification of patterns that are linearly separable. c Simplest version : a single neuron with adjustable synaptic weights and threshold. c After training, a decision surface in the form of a hyperplane is formed between two classes. can classify two classes of patterns. Chapter 3 --- Perceptron 3 Perceptron c Complex version : more than one neuron can classify more than two classes that are linearly separable. Chapter 3 --- Perceptron 4 Architecture of a Perceptron Chapter 3 --- Perceptron 5 Architecture of a Perceptron c A linear combiner followed by a hard limiter. c Output of the linear combiner is where θ is the threshold ∑ =- = p i i i x w v 1 θ Chapter 3 --- Perceptron 6 Architecture of a Perceptron c If the nonlinear function φ j ( v ) is a step function with only two output values (+1 or –1), then the hard limiter output is +1 if v = +ve-1 if v = -ve y = Chapter 3 --- Perceptron 7 Architecture of a Perceptron c For an input x i , if the output y is +1, then it belongs to class C 1 . c Otherwise, it is in class C 2 . c There are two decision regions separated by a hyperplane defined by w x i i i p- ∑ = = θ 1 Chapter 3 --- Perceptron 8 Architecture of a Perceptron c In the...
