Fano resonance is a ubiquitous phenomenon, and it is commonly interpreted as a two-channel interference of the discrete and continuous channels. The present work investigates the Fano profile from a perspective of the temporal evolution of the wave function. By exciting the atom with a δ pulse and calculating the evolution of the wave function, the Fano formula is deduced. The results clearly show that the Fano resonance is of a three-channel interference, which is different from the traditional understanding. The three channels are revealed as the groundcontinuum, ground-discrete-continuum, and a previously unmentioned third channel, i.e., ground-continuumdiscrete-continuum. The present three-channel interpretation can be easily generalized to other physical systems,contributing to a deeper understanding of the Fano profile.

针对现有对齐多模态语言序列情感分析方法常用的单词对齐方法缺乏可解释性的问题,提出了一种用于未对齐多模态语言序列情感分析的多交互感知网络(MultiDAN)。MultiDAN的核心是多层的、多角度的交互信息提取。首先使用循环神经网络(RNN)和注意力机制捕捉模态内的交互信息;然后,使用图注意力网络(GAT)一次性提取模态内及模态间的、长短期的交互信息;最后,使用特殊的图读出方法,再次提取图中节点的模态内及模态间交互信息,得到多模态语言序列的唯一表征,并应用多层感知机(MLP)分类获得序列的情感分数。在两个常用公开数据集CMU-MOSI和CMU-MOSEI上的实验结果表明,MultiDAN能充分提取交互信息,在未对齐的两个数据集上MultiDAN的F1值比对比方法中最优的模态时空注意图(MTAG)分别提高了0.49个和0.72个百分点,具有较高的稳定性。MultiDAN可以提高多模态语言序列的情感分析性能,且图神经网络(GNN)能有效提取模态内、模态间的交互信息。
