Escaping Oversquashing: Addressable and Support-Aware Global Memory for Message Passing Networks
Félix Marcoccia
Virtual nodes are a natural tool against oversquashing: they replace long message-passing paths by a two-hop global route. But when many nodes share one global state, that shortcut…

NetDiff: Graph Diffusion with Improved Global Capabilities to Generate and Update Mobile Network Topologies
Félix Marcoccia, Victor Fagoo, Gilles Monzat +3
We introduce NetDiff, a node-conditioned denoising diffusion model that generates directional link topologies and a two-slot transmit/receive parity for mobile ad hoc networks. Dir…

Improving global awareness of linkset predictions using Cross-Attentive Modulation tokens
Félix Marcoccia, Cédric Adjih, Paul Mühlethaler
This work introduces Cross-Attentive Modulation (CAM) tokens, which are tokens whose initial value is learned, gather information through cross-attention, and modulate the nodes an…
