Description
Technical field
The invention belongs to field of medical technology, more particularly to a kind of summer property skin based on increment type neural network model
Scorching Forecasting Methodology and prognoses system.
Background technology
Currently domestic each health management system arranged be respectively provided with summer dermatitises prediction and evaluation, its use prediction mode be data
Coupling.Its principle is that by system matches fixed data and then personal lifestyle data entry system is shown ill probability.But due to
The complexity of human body and disease, unpredictability, in the form of expression with information for the bio signal, Changing Pattern (Self-variation
Change with after medical intervention) on, it is detected and signal representation, the data of acquisition and the analysis of information, decision-making etc. are many
All there is extremely complex non-linear relationship in aspect.So can only be the data examination of blindness using traditional Data Matching, no
Method judges the logic association and variable between data and data, and the codomain deviation obtaining is big, causes the specificity of system prediction
Very poor, domestic health management system arranged effectively Accurate Prediction cannot be carried out to personal summer dermatitises so current.
Most of before this is all using bp neural network model to summer dermatitises prediction, but when new detection data is produced
It is necessary to train neural network model again when raw, operation efficiency is extremely low.And after system user scale increases, clothes
Business device 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
Summer dermatitises Forecasting Methodology and prognoses system, the present invention by neural network model train predict a large amount of patient in hospital pathology
Data, finds summer dermatitises pathology and summer dermatitises earlier life variations in detail, clinical symptoms, examination criteria value, high-risk
Crowd characteristic, the logic association between this several causes of disease and variable, ultimately form to summer dermatitises illness probability Accurate Prediction
Summer dermatitises pathology neural network model, the present invention pass through gather user's daily life data, its data of active analysis
Periodically, regular suffer from summer dermatitises probability eventually through summer dermatitises pathology Neural Network model predictive user, with
The mode of visual effect reminds user's instant hospitalizing, is constantly repaiied by increasable algorithm when Neural Network model predictive is inaccurate
Positive neural network model, to set up, for each equipment user, the neural network model training for this user, with use
The increase of time, to set up the neural network model that this user is made to measure, accuracy rate is greatly improved.
To achieve these goals, the invention provides a kind of summer dermatitises based on increment type neural network model are pre-
Survey method, comprises the steps:
Step (1), acquisition hospital's summer dermatitises etiology and pathology data source and the daily monitoring data of patient, thus set up the summer
The daily data database of season property dermatitis；
Step (2), the daily data database of summer dermatitises set up according to step (1) are off-line manner to nerve net
Network model is trained, to obtain the summer dermatitises 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 summer dermatitises general in the summer dermatitises pathology neural network model training in input step (2) after normalized
Rate is predicted, obtains summer dermatitises probability, and server sends summer dermatitises probability the nursing of to wired home summer dermatitises
Equipment；
After step (5), the summer dermatitises probability of wired home summer dermatitises care appliances the reception server transmission, sentence
Whether disconnected summer dermatitises probit is more than 0.5, if greater than 0.5, is then judged to that this user obtained summer dermatitises, attention device
Warning, to remind user, if less than 0.5, is then judged to that this user does not obtain summer dermatitises；
Step (6), when user is judged to summer dermatitises, user voluntarily removes examination in hospital, and by inspection result
Send back server by wired home summer dermatitises care appliances, server judges whether inspection result is correct, if inspection
Come to an end fruit mistake, then explanation summer dermatitises pathology Neural Network model predictive is inaccurate, if inspection result is correct, illustrates
Summer dermatitises pathology Neural Network model predictive 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 bar, execute increasable algorithm, to summer dermatitises disease
Reason neural network model carries 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, extracts k bar record from summer dermatitises daily data database table and is trained, every record is a n-dimensional vector,
All data before use first through normalized so as to numerical value is interval in [0,1], then execution following steps are to nerve net
Network model is trained:
1) one n-dimensional vector of input, to neural network model, calculates all of weight vector in neural network model defeated to this
Enter the distance of n-dimensional vector, closest neuron is as won neuron, its computing formula is as follows:
Wherein: wkIt is the weight vector of triumph neuron, | | ... | | for Euclidean distance；
2) weight vector of the neuron in adjustment triumph neuron and triumph neuron field, formula is as follows:

If ei> father node ei× threshold value p, wherein p=0.42, then grow one layer of new subnet from this neuron, will be newly long
The subnet going out 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 summer dermatitises Forecasting Methodology based on increment type neural network model according to claim 1, it is special
Levy and be, if user includes health check-up by other means and checks oneself, learn that oneself has suffered from summer dermatitises, and the wired home summer
The attention device of season property dermatitis care appliances do not warn then it represents that wired home summer dermatitises care appliances judge inaccurate,
Now execution step (6)～(7), wired home summer dermatitises care appliances are sent to object information on server.
6. a kind of prognoses system of summer dermatitises Forecasting Methodology described in employing claim 1～6 is it is characterised in that include intelligence
Energy monitoring device, smart machine data acquisition unit, server and wired home summer dermatitises care appliances, described intelligent monitoring
Equipment is connected with described smart machine data acquisition unit, described smart machine data acquisition unit pass through communication device one with described
Server network communicates, and described wired home summer dermatitises care appliances are passed through communication device two and led to described server network
News.
7. according to claim 7 the prognoses system of summer dermatitises Forecasting Methodology it is characterised in that the described wired home summer
It is provided with attention device on season property dermatitis care appliances.
8. according to claim 7 the prognoses system of summer dermatitises Forecasting Methodology it is characterised in that described intelligent monitoring sets
Standby include Intelligent worn device, Intelligent water cup, Intelligent weight claim, intelligent closestool and Intelligent light sensing equipment.
