http://www.iotword.com/5966.html Webb29 sep. 2024 · The perceptron learning algorithm fits the intuition by Rosenblatt: inhibit if a neuron fires when it shouldn’t have, and excite if a neuron does not fire when it should have. We can take that simple principle and create an update rule for our weights to give our perceptron the ability of learning. horror nachbar was tunWebbThe perceptron learning rule works by accounting for the prediction error generated when the perceptron attempts to classify a particular instance of labelled input data. In particular the rule amplifies the weights (connections) that lead to a minimisation of the error. horror narrative
