Question on architecture

[ovcGIT]

Few clarifications/questions (i'm a beginner, please pardon any basic questions or redirect if an alternate channel is more appropriate)

1. Visualization diagram on GIT: Input gate diagram visualization shows a Ct, is that actually Ct tilde from the paper?
2. Visualization diagram on GIT: There is a tanh activation against Ct in the diagram visualization, is that actually a sigmoid from the paper (text below Eq 15) ?
3. Fig 2 in paper: can you help clarify what are the inputs (red circles on extreme left of Fig 2) - because only one of them has a sigmoid activation. From the paper it seemed like both input / forget had activations if these are what they denote)
4. Fig 2in paper: The KAN layers (called sub-layers) in the paper are these non-recurrent across time steps and NOT connected to each other
5. Fig 3 in paper: Three TKAN layers: looks these not connected? are the outputs simply concatenated
