An overview of LoS prediction.

Each class with at least 50 patients is considered separately as a dataset, CI in the name of the dataset stands for Care Intensity. Accuracy is computed as average MAE—expressed in number of days. Feature selection can be enabled (FeatSel) or not (NoFeatSel), column Class reports the LoS range provided by classification, outliers excluded.每例包含至少50名患者的类别均单独作为一个数据集。数据集名称中的CI（Care Intensity）代表护理强度。准确率以平均绝对误差（Mean Absolute Error, MAE）计算，单位为天数。可启用特征选择（FeatSel）或禁用特征选择（NoFeatSel）；类别列（Class）报告经分类得到的住院时长（Length of Stay, LoS）区间，且已排除异常值。
