Note Gated MLP mechanism. This is depicted in the left-most schematic in Figure 1. An incoming sequence is copied and projected to twice the input dimension. One copy is then passed through a causal convolution, followed by the SiLU/Swish non-linear activation (Ramachandran et al., 2017) and then finally through the selective SSM. The other copy has the SiLU non-linearity applied to it and then gates the SSM output. The gated representation is then projected back to the original dimension D.
