*Neuron*

Node in an artificial neural network (ANN) that receives weighted input data and subsequently generates outputs based on usually non-linear functions.

**ETSI GR ENI 004** node in an ANN that receives weighted input data, adds the data, and produces an output using a non-linear output function.

NOTE: The output function is also called a transfer function or activation function, and represents what portion of the potential action is transmitted.

**ISO/IEC DIS 22989** primitive processing element which takes one or more input values and produces an output value by combining the input values and applying an activation function on the result.

Note 1 to entry: Examples of nonlinear activation functions are a threshold function, a sigmoid function and a polynomial function.

**ISTQB - CTAI Syllabus** neuron: A node in a neural network, usually receiving multiple input values and generating an activation value
