python绘制影像组学训练集、测试集对应的ROC曲线以及瀑布图（rad-score 瀑布图）

 

# 所有数据的瀑布图

tagets_all = df[\'label\']
tagets_all = df.iloc[X_lasso.index][\'label\']

tagets_all.value_counts()

# plt.style.use(\'fivethirtyeight\')

# plt.style.use(\'classic\')
plot_scaler = StandardScaler()
plot_feature = plot_scaler.fit_transform(X_lasso)
results = svm_model.predict_proba(plot_feature)[:,1]
results = results.reshape(-1,1)
scaler = MinMaxScaler((-1,1))
results = scaler.fit_transform(results)
results = (results.flatten())
results[np.where(results < 0)] = resul
