Background technology
Neuron is the elementary cell for forming brain, and the brain of the mankind is that have thousands of individual neurons according to certain rule
Form, for the mankind in order to simulate human brain, the design to artificial neuron is the most important thing, has artificial neuron to form people
Work network, artificial neural network are a kind of mathematical modulos for the structure progress information processing that application is similar to cerebral nerve cynapse connection
Type.In this model, composition network is coupled to each other between substantial amounts of artificial neuron, i.e. " neutral net ", to reach processing
The purpose of information.A kind of kinetic simulation for the distributed parallel information processing algorithm structure for imitating animal nerve network behavior feature
Type., with multichannel input stimulus are received, the part that " excitement " output is produced when exceeding certain threshold value by weighted sum is dynamic to imitate for it
The working method of thing neuron, and the weight coefficient of the structure being coupled to each other by these neural components and reflection strength of association makes
Its " collective behavior " has the various complicated information processing functions.Particularly it is this macroscopically have robust, it is fault-tolerant, anti-interference,
The formation of the flexible and strong function such as adaptability, self study can not only be updated by component performance, and pass through
Complicated interconnecting relation is achieved, thus artificial neural network is a kind of connection mechanism model, has many of complication system
Key character.Artificial neural network be applied to signal transacting, data compression, pattern-recognition, robot vision, knowledge processing and its
Using prediction, evaluation and the combinatorial optimization problem such as decision problem, scheduling, route planning.It can in Control System Design
For simulating controlled device characteristic, search and study control law, realizing fuzzy and intelligent control, therefore to the design of neuron
Very important, because fairly obvious, the shape of neuron is very more, although the mankind classify it, neuron has
Thousands of kinds, therefore different neurons also possesses different functions, the present invention simply devises a kind of artificial neuron, existing
The design very simple of some neurons is single, is exactly all inputs and multiplied by weight, is then added up, subtract valve
Value, then sets activation primitive, passes to next layer of neuron.
The content of the invention
The brain of people is that many neurons are formed, therefore neuron is the elementary cell of neutral net, fairly obvious, nerve
First enormous amount, just there are the neuron of different shape, structure, physiologic character and function, neuron in the different parts of human body
Shape it is very strange very more, although the mankind classify to it, neuron has millions upon millions of kinds, therefore different nerves
Member also possesses different functions, and the present invention simply devises a kind of artificial neuron, due to existing neuron design very
It is simple single, exactly all inputs and multiplied by weight are added up, threshold values is subtracted, then activation primitive is set, pass to
Next layer of neuron, a network is so formed, and so simple design solves many forefathers of the mankind and can not solved
The problem of, tremendous influence is produced to All Around The World, but a kind of this simply artificial neuron meta structure most simply, in real world
The various shapes of neuron, various functions, therefore will invention various functions artificial neuron design, it is a kind of
The design method of more threshold values feedback artificial neurons, it is characterized in that：More threshold values feedback artificial neurons are by input, artificial god
Through member, end-apparatus is selected, output end, feedback line composition, input is such as the input of neuron, reception upper level artificial neuron
Input or the input by other equipment, the effect of artificial neuron be to be added up after value and multiplied by weight input, such as
The cumulative value of fruit is less than threshold values, then artificial neuron would not be activated, without any reaction, if cumulative value is more than valve
Value, then artificial neuron is activated, and cumulative value is just passed to activation primitive simultaneously and selects end-apparatus, selecting end-apparatus can be according to biography
The threshold values passed, those ports are selected to gate, those ports feedback, activation primitive is according to the threshold values transmitted, by activating letter
Number computing, the result of calculating, the passage opened by selecting end-apparatus, next layer of artificial neuron or anti-is passed to from output port
Input is fed to, wherein artificial neuron is using following design, and it is made up of 3 parts, and 1 is accumulator, and its effect is exactly handle
Input is added up, if reaches threshold values, if it exceeds this cumulative value, is just passed to activation primitive simultaneously and selected by threshold values
End-apparatus, 2 be different threshold values, and the design of different threshold values is such, sets minimum threshold values a, a<b<c<D, when the value of input is small
In a, then artificial neuron would not be activated, if the value of input is more than a, artificial neuron is just activated, at this moment inputted
Value will be compared with different threshold values, for example the value inputted is less than d more than c, then will start c values pass to it is sharp
Function living and end-apparatus is selected, select end-apparatus using following design, according to the threshold values transmitted, those can be selected according to this threshold values by selecting end-apparatus
Ports open, those port shutdowns, and select those ports to be fed back according to the threshold values transmitted.
Brief description of the drawings

Implementation
The brain of people has thousands of neuron, and some neurons are fed back by exporting, to adjust neuron oneself, due to this
It is a kind of universal alike, therefore the present invention creates a kind of artificial neuron, more threshold values feedbacks are artificial also according to this alike
Neuron is by input, artificial neuron, selects end-apparatus, and output end, feedback line composition, input is such as the input of neuron
End, the input or the input by other equipment, the effect of artificial neuron for receiving upper level artificial neuron are the values input
Added up with after multiplied by weight, if cumulative value is less than threshold values, then artificial neuron would not be activated, not any
Reaction, if cumulative value is more than threshold values, then artificial neuron is activated, and cumulative value is just passed to activation primitive simultaneously
With select end-apparatus, selecting end-apparatus can select those ports to gate according to the threshold values that passes over, those ports feedback, activation primitive root
According to the threshold values transmitted, by activation primitive computing, the result of calculating, the passage opened by selecting end-apparatus, from output end oral instructions
Pass next layer of artificial neuron or feed back to input, such artificial neuron and the artificial neuron of other functions are joined
Net, form an artificial brain, it is possible to reach the function of imitating human brain, be to adopt due to the artificial neuron of the present invention
The form fed back with more threshold values, therefore more functions can be realized, fewer artificial neuron of the invention can be used, reached
To sufficiently complex network function.
