Description
Technical field
The invention belongs to field of medical technology, more particularly to a kind of coronary heart disease based on increment type neural network model is pre-
Survey method and prognoses system.
Background technology
Currently domestic each health management system arranged be respectively provided with coronary heart disease prediction and evaluation, its use prediction mode be data
Join.Its principle is that by system matches fixed data and then personal lifestyle data entry system is shown ill probability.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 is 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 using traditional Data Matching can only be blindness data examination it is impossible to
Judge the logic association between data and data and variable, the codomain deviation obtaining is big, causes the specificity ten of system prediction
Point poor, domestic health management system arranged effectively Accurate Prediction cannot be carried out to personal coronary heart disease so current.
Most of before this is all using BP neural network model to coronary disease disease forecasting, but when new detection data generation
When it is necessary to train neural network model again, operation efficiency is extremely low.And after system user scale increases, server
Will be unable to complete in time training mission.
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
Coronary heart disease Forecasting Methodology and prognoses system, the present invention by neural network model train predict a large amount of patient in hospital pathology numbers
According to, find coronary heart disease pathology and coronary heart disease earlier life variations in detail, clinical symptoms, examination criteria value, high-risk group's feature, this
Logic association between several causes of disease and variable, ultimately form the coronary heart disease pathology nerve to coronary heart disease illness probability Accurate Prediction
Network model, the present invention passes through to gather user's daily life data, the periodicity of its data of active analysis, regular eventually through
Coronary heart disease pathology Neural Network model predictive user suffers from probability of CHD, immediately reminds user in the way of visual effect
Doctor, constantly revises neural network model when Neural Network model predictive is inaccurate by increasable algorithm, to set for each
Standby user sets up the neural network model training for this user, with the increase of use time, to set up to this customer volume
Body neural network model customized, accuracy rate is greatly improved.
To achieve these goals, the invention provides a kind of coronary disease disease forecasting side based on increment type neural network model
Method, comprises the steps:
Step (1), acquisition hospital coronary etiology and pathology data source and the daily monitoring data of patient, thus set up coronary heart disease
Daily data database;
Step (2), the daily data database of coronary heart disease set up according to step (1) are off-line manner to neutral net mould
Type is trained, to obtain the coronary heart disease pathology neural network model training;
Step (3), by intelligent monitoring device, the daily life data of user is acquired, and will collection daily life
Live data sends to server, and server preserves the daily life data of user to the daily data logger of user;
Step (4), from the daily data logger of user, extract same day data, form n-dimensional vector, and n-dimensional vector is done
Carry out probability of CHD prediction in the coronary heart disease pathology neural network model training in input step (2) after normalized,
Obtain probability of CHD, server sends probability of CHD to wired home coronary heart disease nursing equipment;
After step (5), the probability of CHD of wired home coronary heart disease nursing equipment the reception server transmission, judge coronary heart disease
Whether probit is more than 0.5, if greater than 0.5, is then judged to that this user obtained coronary heart disease, attention device warns to remind user,
If less than 0.5, then it is judged to that this user does not obtain coronary heart disease;
Step (6), when user is judged to coronary heart disease, user voluntarily removes examination in hospital, and inspection result is passed through
Wired home coronary heart disease nursing equipment sends back server, and server judges whether inspection result is correct, if inspection result is wrong
By mistake, then explanation coronary heart disease pathology Neural Network model predictive is inaccurate, if inspection result is correct, coronary heart disease pathology god is described
Through network model's prediction accurately;
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 bar, execute increasable algorithm, to coronary heart disease pathology god
Carry out dynamic corrections through network model;
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, extracts k bar record from coronary heart disease daily data database table and is trained, every record is a n-dimensional vector, owns
Data before use first through normalized so as to numerical value is interval in [0,1], then execution following steps are to neural network model

Wherein:WiFor the weight vector of neuron i, CiThe set constituting for all input vectors being mapped to neuron i;
Wherein:niRepresent to fall that label is the number of samples of i on neuron, m represents to fall the total of label data on neuron
Number, T represents to fall the sample label species set on neuron;
Then judge:
If MQE>QE × threshold value q of father node, wherein q=0.71, then insert a line neuron in this SOM, go 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 this neuron, will be new
The subnet growing increases in the subnet queue of Layer+1 layer;
If being not inserted into new neuron in SOM also do not grow new subnet, illustrate that the training of this subnet completes;
7) for all 2 × 2 structures SOM of the Layer+1 layer 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.
5. a kind of coronary heart disease Forecasting Methodology based on increment type neural network model according to claim 1, its feature exists
