Learning in Simple Neurons (2) Neuron given random initial weights At starting state, neuron knows nothing Present an H Neuron computes the weighted sum of inputs Compare weighted sum with threshold If exceeds threshold, output a 1 otherwise a 0 If output is 1, neuron is correct Do nothing Otherwise if neuron produces a 0 Increase the weights so that next time it will exceed the threshold and produces a 19 Learning in Simple Neurons (2) • Neuron given random initial weights. – At starting state, neuron knows nothing. • Present an H. – Neuron computes the weighted sum of inputs. – Compare weighted sum with threshold. – If exceeds threshold, output a 1 otherwise a 0. • If output is 1, neuron is correct. – Do nothing. • Otherwise if neuron produces a 0. – Increase the weights so that next time it will exceed the threshold and produces a 1
