understanding of the results of the model, so that we can make some adjustments to the model training. Can not blindly trust the results of model training. To sum up: In practical application, the hidden data is used more, the data processing should pay special attention to the cleaning of the exception, the proper sample sampling (over sampling or descending sampling) can adjust the positive and negative sample ratio, which is advantageous to the algorithm to train the real meaningful model; W

classification algorithms may be poor, and the computational amount is also larger.5. Application examplesHere is a practical application of chestnuts, the basic method is heuristic search (sequential addition) + relevance criteria (CHI-square test, maximum entropy) + quasi-call stop criteria. The procedure is described in detail below.STEP1: Counts the chi-square value of each feature.STEP2: Take the eigenvalues of the TOPN.STEP3: Bring into the model training and calculate the accuracy and re
