🧵"Neural Message Passing on Attention Graphs for Hallucination Detection" at #ICLR2026 !

🕸️We apply GNNs on the structured data LLMs produce as they generate text (e.g. attentions) to predict their errors.

🌟 GLOW is back tomorrow, Oct 29th, 5pm CEST on Zoom!

- Celia Rubio-Madrigal will talk about feature-similarity-based rewiring (openreview.net/pdf?id=g6v09Vx…)

- Lorenz Kummer will show how to attack GNNs with bit-flips (dl.acm.org/doi/pdf/10.114…)

Plenty of discussions as usual ☺️

GLOW is "so back" after the summer break!

Tomorrow: an interaction-heavy, plenary session on oversmoothing/squashing, homo/heterophily and their interplay.

Tune in! ☺️

(spoiler: prominent researchers on the topics will also join Adrián and Federico in the discussions 😇)

👤 with Adrián & Federico.
🔥 Discussion-heavy continuation of our last packed sessions.
📅 Sep 3rd, 5pm CEST on Zoom!
