The Method of Using a Small Number of Samples to Integrate the Model of Predicting Drug Addicts

WANG Can;School of Mathematics, Chengdu Normal University;  
In order to accurately locate the suspected individuals,first,selection of samples and use the improved feature scaling method to get the basic sample set of the combined ascending dimension.Then the positive samples are sampled,while the negative samples are sliced,to correct the imbalance of positive and negative sample sets.Finally the neural network is applied to integrate the forecast model of drug addicts,the training as well as validation are conducted by way of the positive and negative sample sets,the paper comes up with"the evaluation method of the three rates"being based on the research precision rate,accuracy rate and recall rate to evaluate model and predict conclusion simulation verification was carried out and give the relevant policy recommendations.
