LTI SSMs: S4, S4D, S5 as discretized continuous systems
Three discrete realizations of the same continuous SSM; convolutional vs recurrent views.
LTI SSMs: S4, S4D, S5 as discretized continuous systems
This chapter is planned. See the chapter-at-a-glance (foundations §3) for the full design; the crosswalk (foundations §22) maps this chapter to the relevant post_transformers/roadmap.md weeks.
