Derived sheaf theory and persistence; without words? From my recent talk at the London TDA seminar! Open problem: If I give you a derived sheaf on a poset, give me a sequence of extensions of local systems supported on subposets, which produces a quasi-isomorphic complex.

Bispectral Neural Networks go to #ICLR2023! In this work, we present a new neural network architecture capable of learning unknown groups purely from the symmetries implicit in data —with @cashewmake2, Bruno Olshausen, and Christopher Hillar 1/17

Exciting news! Our latest publication by @karlahuljev et al. shows a hydraulic feedback loop that promotes embryonic axis formation in #zebrafish. Check our tweetorial for a sneak peek. @Dev_Cell: sciencedirect.com/science/articl…

Weekend project: flocking simulation via alpha complexes. The more I learn about emergence the cooler I think it is!

What derived sheaf calculation should we do next? The pushforward of the constant sheaf by the Hopf fibration is my fav so far github.com/OnDraganov/desc
