The concept of perceptron
The perceptron is that's a device that makes decisions by weighing up evidence it. ( the greater the weight, the greater the share of influence; the introduction of the concept of weighting the importance of the input relative to the output of representation)

perception of work as follows:

the corresponding mathematical formula

Conversion of the minor type, so that b is equivalent to -threshold

there,

Perceptron basic logic functions,

the image above is equivalent to the NAND
using NAND adder built as

a logic circuit of FIG neurons replaced

simplified (two into one output, the weight change)
