Embodiment 1
[0060] The method for drug risk classification based on naive random oversampling and support vector machine includes the following steps:
[0061] Step 1: Query the factors associated with the risk of adverse drug reactions in the spontaneously reported data, and establish the I 1 , I 2 , I 3 as an indicator of risk;
[0062] Step 2: Calculate the three index values of each drug based on the self-reported data;
[0063] The third step: taking drugs as objects and using three indicators as characteristics to establish a drug risk matrix;
[0064] Step 4: According to the National Essential Drugs List, classify the two types of drugs in the drug risk matrix. Prescription drugs are marked as "0" and non-prescription drugs are marked as "1". The marked data set is the original data, which is recorded as D 0 ;
[0065] Step 5: Since the number of prescription drugs is much larger than that of non-prescription drugs, the sample expansion of non-prescription drug data in the ...
