Sampling methods including over-sampling, under-sampling were taken to make up the shortage caused by the imbalanced data.
采用过抽样、欠抽样技术来弥补数据类别分布不平衡对模型性能的不利影响。

By choosing sampling signals by the way of the over-sampling, the metrical speed of dynamic automotive metrical can be increased when holding the accuracy of weigh-in-motion within 1%.
通过过采样方法处理后的采样信号，使动态轴重式汽车衡在保证其称量达1%精度时，提高称重过车速度。
