Summary

Description
English: An artificial neuron. It has input nodes , weights . The input signals get multiplied with the weights. The results are summed up. Then the activation function is applied (e.g. sigmoid, tanh, ReLU, ...). This is then the output of the artificial neuron. Overall, the perceptron unit is a function . Typical choices for activation functions are the sigmoid function or ReLU .

The input is called the bias and is constant 1, so .

Deutsch: Ein künstliches Neuron. Es hat Eingabeknoten , Gewichte . Die Eingabesignale werden jeweils mit den Gewichten multipliziert. Die Ergebnisse werden aufsummiert. Dann wird auf die Summe die Aktiviertungsfunktion (z.B. die Sigmoid-Funktion, tanh, ReLU, ...) angewendet. Die Perzeptron-Einheit beschreibt also eine Funktion . Zwei typische Aktivierungsfunktionen sind die Sigmoidfunktion und ReLU .

Der Eingabeknoten wird Bias genannt und ist konstant 1, also .
