这里我的选择是用Random Forest Model. 首先, RF可以很好的处理多特征的数据 , 其次RF可以顺便做特征选择。(可以用别的model,欢迎大家来讨论) from sklearn.ensemble import RandomForestClassifier 因为我们不可能将dataset里所有的特征都拿来fit model,所以我们要进行特征选择。 根据我们之前对于数据的快速分析, 我们...
The results show that linear regression (LR) has the highest accuracy and the most stable performance, while decision tree is the worst model. Also, in terms of the operation efficiency of the system, LR has the best performance, followed by support vector machine and random forest algorithm....

Machine learning classifiers This study proposes a novel multi-class random forest model based on machine learning. The results of this model are compared with state-of-art-models i.e. Naïve Bayes (NB), Support Vector Machine (SVM), Decision Tree (C5.0) and Random Forest (RF). The rati...
from sklearn.model_selection import train_test_split X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=.2,random_state=0) 关于train_test_split的用法参考如下: 一般形式: train_test_split是交叉验证中常用的函数,功能是从样本中随机的按比例选取train data和testdata,形式为...
