We presented DSA at NeurIPS in 2023 (more extensions to come, stay tuned!) x.com/neurostrow/sta…

The basic idea of DSA: approximate your dynamics so that comparison is tractable. This is backed by Koopman Operator Theory and relates to work done by @wredman4 , @IgorMezic InputDSA naturally extends DSA—we can compare intrinsic dynamics, effect of input, or both jointly! 3/

Applying to grad school is hard. The expectations for essays are murky, and not everybody comes from a wealthy institution with resources needed to optimize an application. If you're applying to grad school now, please reach out and I'll be happy to help you edit your essays.

How can we understand the way sequence models choose to combine info in their context to make good predictions? In our new @icmlconf workshop paper, @adamjeisen , @FieteGroup and I provide a new theoretical lens from dynamical systems: delay embeddings arxiv.org/abs/2406.11993

I'll be presenting this work today (Tuesday) in the 5:15-7:15pm poster session, #416! Come through if you want to chat about Koopman operators, neural manifolds / dynamics, or just to say hi!

DSA combines recent advances in data-driven dynamical systems theory and shape analysis to tease apart dynamics and geometry. We learn a high-dimensional linear embedding of nonlinear systems using HAVOK, a variant of Dynamic Mode Decomposition from @eigensteve. 3/

We don’t view DSA as a replacement for current similarity metrics but rather as a complement that emphasizes a distinct component of neural computation—time. 9/

A paper from @ItsNeuronal and @niru_m showed that different RNN architectures trained on this task have the same attractor topology, but statistical shape metrics can distinguish them. We replicate their result and show that DSA identifies each architecture as equivalent. 5/

Had a lot of fun writing about @courellis 's and @UeliRutishauser 's amazing research!

Very appreciative of all the interest surrounding this post! I’ll do my best to get through them all but for now I have to ask y’all to hold off contacting me for a bit.
