Description
Technical field
The invention belongs to field of medical technology, more particularly to a kind of hypertension based on increment type neural network model is pre-
Survey method and forecasting system.
Background technology
It is current domestic it is each it is health management system arranged be respectively provided with hypertension prediction and evaluation, the prediction mode that it is used is data
Match somebody with somebody.Its principle is that then personal lifestyle data entry system is shown into ill probability by system matches fixed data.But due to people
The complexity of body and disease, unpredictability, in the form of expression of bio signal and information, Changing Pattern (Self-variation with
Change after medical intervention) on, it being detected and signal representation, the data of acquisition and the analysis of information, decision-making etc. are all multi-party
All there is extremely complex non-linear relationship in face.So the use of traditional Data Matching can only be the data examination of blindness, it is impossible to
Judge the logic association and variable between data and data, the codomain deviation for obtaining is big, causes the specificity ten of system prediction
It is point poor, domestic health management system arranged effectively Accurate Prediction cannot be carried out to the hypertension of individual so current.
Most of before this is all to use BP neural network model to hypertension prediction, but when new detection data generation
When, it is necessary to neural network model is trained again, and operation efficiency is extremely low.And after system user scale increases, server
Will be unable to complete training mission in time.
The content of the invention
The purpose of the present invention is that and overcomes the deficiencies in the prior art, there is provided one kind is based on increment type neural network model
Hypertension Forecasting Methodology and forecasting system, the present invention predicts a large amount of patient in hospital pathology numbers by neural network model training
According to, hypertension pathology and hypertension earlier life variations in detail, clinical symptoms, examination criteria value, people at highest risk's feature are found, this
Logic association and variable between several causes of disease, ultimately forms the hypertension pathology nerve to Hypertension probability Accurate Prediction
Network model, the present invention by gathering user's daily life data, the periodicity of active analysis its data, it is regular eventually through
Hypertension pathology Neural Network model predictive user's suffers from hypertension probability, and user is reminded in the way of visual effect immediately
Doctor, constantly corrects neural network model, to set for each when Neural Network model predictive is inaccurate by increasable algorithm
Standby user sets up the neural network model trained for the user, with the increase of use time, to set up to the customer volume
Body neural network model customized, accuracy rate is greatly improved.
To achieve these goals, the invention provides a kind of hypertension prediction side based on increment type neural network model
Method, comprises the steps:
Step (1), acquisition hospital hypertension pathogeny pathological data source and the daily monitoring data of patient, so as to set up hypertension
Daily data database;
Step (2), according to step (1) set up the daily data database of hypertension off-line manner to neutral net mould
Type is trained, to obtain the hypertension pathology neural network model for training;
Step (3), the daily life data of user are acquired by intelligent monitoring device, and will collection daily life
Live data is sent to server, and server preserves the daily life data of user into the daily data logger of user;
Step (4), from the daily data logger of user same day data are extracted, form n-dimensional vector, and n-dimensional vector is done
It is general hypertension degree of danger to be carried out in the hypertension pathology neural network model trained in input step (2) after normalized
Rate predicts, obtains hypertension probability results array P, and server is by corresponding hypertension degree of danger value W of maximum probability in array P
Send wired home hypertension care appliances to;
After step (5), hypertension degree of danger value W of wired home hypertension care appliances the reception server transmission, sentence
Whether broken height blood pressure degree of danger value W is more than or equal to 3, and if greater than equal to 3, then attention device is warned to remind user, if little
In 3, then attention device is not warned;
Step (6), when user receive attention device warn when, user voluntarily removes examination in hospital, and inspection result is passed through
Wired home hypertension care appliances send back server, and server judges whether inspection result is correct, if inspection result is wrong
By mistake, then illustrate that hypertension pathology Neural Network model predictive is inaccurate, if inspection result is correct, illustrate hypertension pathology god
The prediction of Jing network models is accurate;
Step (7), when inspection result mistake, from the daily data logger of user extract m days in record preserve to
In incremental data table, when the record quantity in incremental data table is more than h bars, increasable algorithm is performed, to hypertension pathology god
Jing network models carry out dynamic corrections;
Step (8), repeat step (3)~(7).
Further, the input layer of neural network model is n node, and hidden layer number is n*2+1, and output layer is 1
Node, k bars record is extracted from the daily data database table of hypertension and is trained, and per bar, record is a n-dimensional vector, is owned
Data are using front first Jing normalizeds so as to which numerical value is interval in [0,1], then perform following steps to neural network model
It is trained:
1) n-dimensional vector is input into neural network model, calculate all of weight vector in neural network model defeated to this
Enter the distance of n-dimensional vector, closest neuron is triumph neuron, and its computing formula is as follows:
Wherein:WkIt is the weight vector of triumph neuron, | | ... | | for Euclidean distance;
2) weight vector of triumph neuron and the neuron in triumph neuron field is adjusted, formula is as follows:
Wherein:WjT () is neuron;Wj(t+1) it is to adjust the weight vector after front and adjustment;J belongs to triumph neuron neck
Domain;α (t) is learning rate, and it is the function gradually successively decreased with the increase of iterations, and span is [0 1], through multiple
It is 0.71 that Optimal learning efficiency is chosen in experiment;DjIt is the distance of neuron j and triumph neuron;σ (t) is the letter for successively decreasing over time
Number;Each time all input n-dimensional vectors are all input in neural network model and are trained by iteration, when the iteration for reaching regulation
After number of times, neural network model training terminates.
Further, inspection result is sent back wired home hypertension care appliances the form of the object information of server
For:{ the hypertension degree of danger value of the actual judgement of doctor }, whether server judges inspection result after object information is received
Correctly.
Further, it is to the increasable algorithm that hypertension pathology neural network model carries out dynamic corrections:
In incremental data table per bar vector V { V1,V2,…,Vn, it is sent in neural network model learning function
Row study, learning procedure is as follows:

6) quantization error QE of each neuron in the neural network model after calculating is adjustedi, neuronal messages entropy EiAnd son
The average quantization error MQE of net, formula is as follows:
Wherein:WiFor the weight vector of neuron i, CiFor the set that all input vectors for being mapped to neuron i are constituted;
Wherein:niRepresent fall on neuron label for i number of samples, m represents the total of label data on neuron
Number, T represents the sample label species set on neuron;
Then judge:
If MQE>QE × threshold value q of father node, wherein q=0.71 then inserts a line neuron in the SOM, goes to step 4);
If Ei>The E of father nodei× threshold value p, wherein p=0.42, then grow one layer of new subnet from the neuron, will be new
The subnet for growing increases in the subnet queue of Layer+1 layers;
If new neuron is not inserted into SOM does not grow new subnet yet, illustrate that the subnet training is completed;
7) for all 2 × 2 structures SOM of the Layer+1 layers newly expanded out, iteration operating procedure 3)~5) it is re-started
Training, until neural network model no longer produces new neuron and new layering, whole training terminates.
