Description
Technical field
The invention belongs to field of medical technology, more particularly to a kind of viral skin based on increment type neural network model
Scorching Forecasting Methodology and forecasting system.
Background technology
Currently domestic each health management system arranged be respectively provided with viral dermatitis 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 viral dermatitis so current.
Most of before this is all using BP neural network model to viral dermatitis 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
Viral dermatitis Forecasting Methodology and forecasting system, the present invention by neural network model train predict a large amount of patient in hospital pathology
Data, finds viral dermatitis pathology and viral dermatitis 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 viral dermatitis illness probability Accurate Prediction
Viral dermatitis pathology neural network model, the present invention pass through gather user's daily life data, its data of active analysis
Periodically, the regular ill contact dermatitis probability eventually through viral dermatitis 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 viral dermatitis based on increment type neural network model are pre-
Survey method, comprises the steps：
Step (1), acquisition hospital's viral dermatitis etiology and pathology data source and the daily monitoring data of patient, thus set up disease
The daily data database of contact dermatitis；
Step (2), the daily data database of viral dermatitis set up according to step (1) are off-line manner to nerve net
Network model is trained, to obtain the viral dermatitis 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 viral dermatitis general in the viral dermatitis pathology neural network model training in input step (2) after normalized
Rate is predicted, obtains viral dermatitis probability, and server sends viral dermatitis probability the nursing of to wired home viral dermatitis
Equipment；
After step (5), the viral dermatitis probability of wired home viral dermatitis care appliances the reception server transmission, sentence
Whether disconnected viral dermatitis probable value is more than 0.5, if greater than 0.5, is then judged to that this user gets sick contact dermatitis, attention device
Warning, to remind user, if less than 0.5, is then judged to that this user does not obtain viral dermatitis；
Step (6), when user is judged to get sick contact dermatitis, user voluntarily removes examination in hospital, and by inspection result
Send back server by wired home viral dermatitis care appliances, server judges whether inspection result is correct, if inspection
Come to an end fruit mistake, then explanation viral dermatitis pathology Neural Network model predictive is inaccurate, if inspection result is correct, illustrates
Viral dermatitis 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 viral dermatitis disease
Reason neural network model carries out dynamic corrections；
Step (8), repeat step (3)～(7).
