New blog post about an exploratory project that’s been stuck in my head for a while.

Directed simplicial complexes from coherent counterfactual ablations ... as a way to trace superpostions of distributed feature representations on polysemantic neurons in artificial neural nets.

The second article:

Looks at adiabatic solutions of the Haydys-Witten equations and relates them to paths in the moduli space of EBE monopoles. This suggests a relation between Haydys-Witten instanton Floer homology and symplectic Khovanov homology.

The first article:

Introduces a one-parameter family of instanton Floer homology groups for four-manifolds, using the θ-Kapustin-Witten and Haydys-Witten equations. A conjecture by Witten links this to Khovanov homology for knots.
