In my previous post on dynamic mode decomposition, I discussed the foundations of DMD as a means for linearizing a dynamical system123. In this post, I want to look at a way in which we can use rank-updates to incorporate new information into the …
In the next two posts, I want to talk briefly about an algorithm called Dynamic Mode Decomposition (DMD). DMD is a spatiotemporal modal decomposition technique that can be used to identify spatial patterns in a signal (modes), along with the time …
