Description

Immunological network categorizing system and method with cell differentiation is oriented to based on fictitious force
Technical field
It is more particularly to a kind of to be oriented to based on fictitious force and thin the present invention relates to a kind of immunological network categorizing system and method The immunological network categorizing system and method for born of the same parents' differentiation.
Background technology
Artificial immune network refers to a kind of method that the memory cell for being capable of covering problem space is trained according to antigen, this In the problem of space just refer to feature space belonging to sample information, even sample data is bivector type, then problem space Exactly include the two dimensional sample space of antigen sample set.
Earliest artificial immune network model is aiNet (artificial immune system), is described in detail below step:
Step 1: to each antigen:First, the affinity of antibody randomly generated is calculated, the antibody of n high-affinity is chosen; 2nd, n high-affinity antibody produces clonal antibody collection D according to affinity, and for each antibody, its affinity is higher, clones number It is more;3rd, progress affinity maturation direct to D is processed as in D*, i.e. D each antibody and become according to formula C=C-a (C-X) Different, affinity is higher, and aberration rate is smaller;Wherein C is network cell matrix, and X is antigen matrix, and a is learning rate or maturing rate, Set according to Ag-Ab affinity, affinity is higher, and a is smaller;4th, the affinity of each antibody in antigen and D* is obtained;5th, from A certain proportion of antibody with high-affinity is selected in D*, clone's memory cell is put into and concentrates;6th, obtain memory and concentrate antibody Similarity, carry out clone inhibition;7th, will remember concentrates antibody to be stored in total memory antibody collection;
Step 2: seeking the similarity of total memory cell antibody, network suppression is carried out;
Step 3: immunological network antibody tormation;
Step 4: end condition:When antibody cell collection reaches specified book, or reach default maximum iteration.
AiNet immune network models are the clustering for data earliest, afterwards, and part research has been carried out accordingly to it Ground extends to realize the classification to data sample information.
At present, it is the AINC algorithms of the propositions such as Liu Ruochen with the present invention most close artificial immune network sorting technique, The key technology of this method mainly includes data prediction, netinit, antibody is affine function, network mechanism of proliferation, hypermutation Different and network competition mechanism.
Data prediction, the purpose of data prediction is in order that each dimensional feature of data occupies identical in classification processing Proportion.Its specific data prediction is following (11):
Wherein x represents the pending data read in, and Min (x), Max (x) refer to the maximum in being arranged belonging to some data respectively And minimum value.
The initialization of immunological network, the initialization of immunological network includes generation and the weight matrix of initial antibodies cell mass Produce.The average of training sample of all categories is mainly taken as initial antibodies cell;Assuming that pending data set will be divided into C Class, then W is exactly a C rank square formation, i.e., whereinB is the value and b >=1 being previously set.
The affinity function of antibody affinity function, antibody and antigen uses following formula (12) such as to carry out:
Wherein KiRepresent the number of the i-th class training sample, improved purpose be in order to improve the priority of this classification antigen, prijRepresent to BiThe correct identification number of jth class training sample, K represents all training sample numbers.
Network mechanism of proliferation, after somatic cells are resisted first by the propagation scale increment set in advance, resists i-th Body cell BiProliferating population is designated as Mi, pg is that network breeds scale, then in each iteration all to MiIt is updated, evolution Excellent individual replaces the minimum antibody cell of original affinity in clone afterwards.
Hyper mutation, mainly computing with words two parts between variation and cell constitute.Computing with words between cell is Refer to MCiIn all antibody cells each dimensional feature value within occur random exchange.En represents MCi(j) it is corresponding reinforcing antigen or Person is and MCi(j) generic antigen is (when the random number of generation is less than or equal to pmWhen, for reinforcing antigen;Otherwise, it means that after Person), n is category label, n=1,2 ..., C, the variation formula such as following formula (13) of j-th of antibody cell, (14):
MCi(j)=MCi(j)-a(MCi(j)-En(k))......(13)
A=srand | | MCi(j)-En(k)||·pm......(14)
Wherein pmFor mutation probability, s is an auto-adaptive parameter, En (k) represent a selected reinforcing antigen or It is selected and the generic antigen of antibody cell, k=| randL |, | x | represent to being rounded under x, L is represented in En Comprising antigen number.
With reference to above-mentioned key technology, the specific implementation and step of AINC methods are as follows:
Step 5: reading sample, sample data is pre-processed, the classification number selection training sample according to needed for classification Area, if class categories number is C, chooses each training fields of C;
Step 6: initialization antibody cell and weight matrix W;
Step 7: network evolution;Tenth, calculating antibody BiAffinity, choose correspondence BiIntensive training sample (reinforcing is anti- It is former) Agoi, iteration=0;11, network is bred, to BiReplicated by propagation scale pg, generate BiCell pool Mi, Then i=i+1;Return to 3.1, End if;12, by clone sizes to MiIn individual by affinity size carry out Antibody cell after clone, clone is designated as MCi;13, to MCiHyper mutation is carried out, MC is obtainedi';14, to MCi' in it is each Antibody cell calculates its affinity and its corresponding reinforcing antigen;15, MC is selectedi' in affinity it is high individual to itself The antibody of low affinity is updated;
Step 8: output network, is classified.
AINC methods mainly use hyper mutation method when selection builds the immunological network for classifying, while using Be thought that a classification is only recognized by antibody cell.As above two ways has certain limitation, tool Body surface is now as follows:17, in the case where problem space is complex, a class label is concluded only with an antibody Situation when it is inaccurate, higher rate of false alarm will be caused, i.e., misrepresented deliberately the classification of sample for other class labels;18, adopt The mode evolved with random variation is likely to result in immunological network and builds time-consuming higher defect.
