翻译MR-TSOM包含MR和FFT-TSOM其中MR是全变分型乘法正则化而PDA求解的损失函数是基于LSIE反演模型建模的且使用全变分型加法正则化、稀疏正则化和介质物理边界三者组合的惩罚。

The MR-TSOM includes MR and FFT-TSOM, where MR stands for total variation-based multiplicative regularization, and the loss function solved by PDA is modeled based on the LSIE inversion model, and it uses a combination of total variation-based additive regularization, sparse regularization, and physical boundary of the medium as penalties.
