Instead of fields that point to data, the actions point to (dataset) methods.

注意，字段指向的是数据，而动作指向的是(dataset)方法。

The upper limit and the lower limit is computed first when inducing the CPTs from uncompleted dataset, and the point value is estimated by some method such as averaging.

对基于不完备样本集的参数学习，则首先计算参数值的上限值和下限值，再利用某种策略，如平均值法，得到参数的最终估计值。
