Improving Equivariant Networks with Probabilistic Symmetry Breaking

no code implementations27 Mar 2025 Hannah Lawrence, Vasco Portilheiro, Yan Zhang, Sékou-Oumar Kaba

However, equivariant networks cannot break symmetries: the output of an equivariant network must, by definition, have at least the same self-symmetries as the input.

On the Identifiability of Causal Abstractions

no code implementations13 Mar 2025 Xiusi Li, Sékou-Oumar Kaba, Siamak Ravanbakhsh

We introduce a theoretical framework that calculates the degree to which we can identify a causal model, given a set of possible interventions, up to an abstraction that describes the system at a higher level of granularity.
