Neuron
What is a neuron? from the point of view of function image, this is a straight line.
What is the use of a neuron? To illustrate the use, we must give an application scenario: classification. A neuron is a straight line, equivalent to the Chu River Han boundary, can be divided between red chess and green chess, at this time it is a classifier. Therefore, in linear scenarios, a single neuron can achieve the function of classification, it can always learn a suitable line to distinguish the two types of elements.
