用专业学术英语翻译或优化下面的话：然而该方法受限于类别依赖的假设无法应用于样本依赖噪音数据同时其效果依赖于准确的噪音后验概率估计当估计不准时算法的效果会受到损害。基于此方法我们对其进行了改进扩展形成了新方法新方法可以在保留结构简洁的同时可以应用于多种不同的噪音类型而不再限制于类别依赖噪音。

However, this method is limited by the assumption of category dependence and cannot be applied to sample-dependent noisy data. Additionally, its effectiveness relies on accurate estimation of the posterior probability of noise, and when the estimation is inaccurate, the algorithm's performance is compromised. Building upon this method, we have improved and extended it to form a new approach. The new approach retains structural simplicity while being applicable to various types of noise, no longer limited to category-dependent noise.
