  Overview of the RE-SORT framework, which contains two key components: I. a multilevel stacked recurrent (MSR) structure and II. a spurious correlation elimination (SCE) module. The deep and shallow stacked recurrent interactions (D-SR and S-SR) in the MSR structure and the SCE module are colored blue, green, and purple, respectively. The D-SR and S-SR streams contain M and N (M $>$ N) stacked blocks, and ``$Q_i$'', ``$K_i$'', and ``$V_i$'' denote the query, key, and value, respectively, for $i$-th block. The attenuation coefficient is denoted by $r_i$ for $i$-th block (dotted lines). The outputs $F_d$ and $F_s$ are concatenated (``C'') as the input of the SCE and the CTR predictor, which is visualized to show the spurious correlation elimination process guided by the SCE module. ``RKHS'' denotes the reproducing kernel Hilbert space. The SCE procedure is explained in Algorithm~\ref{RE-SORT}.}
