Mean performance of the baseline alcohol-outlet only linear regression vs the proposed LASSO-based POI model across 100 random test/train splits.

Mean performance of the baseline alcohol-outlet only linear regression vs the proposed LASSO-based POI model across 100 random test/train splits.在100次随机训练/测试划分下，仅纳入酒类销售点变量的基准线性回归模型与所提出的基于LASSO的兴趣点（Point of Interest，POI）模型的平均性能表现对比。
