   The first version of this presentation (v1) contained a mistake. It reported the shares of electricity generation by source for Africa as a whole in 2023, based on data from the International Energy Agency. The corresponding figures for South Africa in 2023 are, of course, different and are reported here. The relevant figure has been corrected in the second version of the presentation (v2).

3. Message-passing on hypergraphs: detectability, phase transitions and higher-order information

   Slide number four contains a mistake that I also reiterated verbally during the presentation. I realized my mistake after reading this work. In the talk, I was not sufficiently explicit about what I meant when stating that “hypergraphs and graphs are different objects”. To clarify: I agree that every hypergraph admits an equivalent bipartite graph representation. Indeed, this equivalence is the modeling and algorithmic foundation of our paper. My intended point was different and simpler. Specifically, a hypergraph generally induces a factor graph that differs from the hypergraph’s clique expansion.
