将下面的话翻译成学术英文：上一小节提到之前的转移矩阵方法难以适用到样本依赖噪音并当噪音概率后验估计不准时效果不佳这主要是由于概率A与B分布之间存在差距我们针对此希望提出一个量来衡量。

In the previous section, it was mentioned that the previous transfer matrix method is difficult to apply to samples with dependent noise and performs poorly when the posterior estimation of noise probability is inaccurate. This is mainly due to the discrepancy between the probability distributions of A and B. To address this issue, we aim to propose a metric to measure this discrepancy.
