    en.wikipedia.org/wiki/Neural_network_(machine...

    An ANN consists of connected units or nodes called artificial neurons, which loosely model the neurons in the brain. Artificial neuron models that mimic biological neurons more closely have also been recently investigated and shown to significantly improve performance. These are connected by edges, which model the synapses in the brain. Each ...

    en.wikipedia.org/wiki/Artificial_neuron

    Artificial neurons are designed to mimic aspects of their biological counterparts. However a significant performance gap exists between biological and artificial neural networks. In particular single biological neurons in the human brain with oscillating activation function capable of learning the XOR function have been discovered. [6]

    Animated confocal micrograph, showing interconnections of medium spiny neurons in mouse striatum. A neural network, also called a neuronal network, is an interconnected population of neurons (typically containing multiple neural circuits). [1] Biological neural networks are studied to understand the organization and functioning of nervous systems.

    The concept of artificial neural network (ANN) was introduced by McCulloch, W. S. & Pitts, W. (1943) [16] for models based on behavior of biological neurons. Norbert Wiener (1961) [ 17 ] gave this new field the popular name of cybernetics , whose principle is the interdisciplinary relationship among engineering, biology, control systems, brain ...

    While individual neurons are simple, many of them together in a network can perform complex tasks. There are two main types of neural network. In neuroscience , a biological neural network is a physical structure found in brains and complex nervous systems – a population of nerve cells connected by synapses .

    The input neurons standardizes the value ranges by subtracting the median and dividing by the interquartile range. The input neurons then feed the values to each of the neurons in the hidden layer. Hidden layer: This layer has a variable number of neurons (determined by the training process). Each neuron consists of a radial basis function ...

  9. Biological neuron model - Wikipedia

    en.wikipedia.org/wiki/Biological_neuron_model

    Biological neuron models, also known as spiking neuron models, [1] are mathematical descriptions of the conduction of electrical signals in neurons. Neurons (or nerve cells) are electrically excitable cells within the nervous system , able to fire electric signals, called action potentials , across a neural network.
