5/ 📈 Key benefits:
✅ Learns a more robust relevance estimation function by modeling the joint distribution over features + labels
✅ Matches inference cost of discriminative models
✅ Outperforms discriminative baselines on standard LTR datasets in our experiments.

1/ Excited to share that PeerPrism from https://t.co/B3yCv1pm8N has been accepted at #SIGIR2026
A benchmark for reality of today’s peer review, where reviewers draft the reviews, LLMs refine it, and “was this written by AI?” is no longer a yes/no question.

I’ve been dreaming of my first @ACMSIGIR since I became a student.

Seems the universe has other plans:
📍 2024 (Washington DC) 🚫 Travel Ban
📍 2026 (Melbourne) 🚫 Travel Ban
📍 2027 (Silicon Valley) 🚫 Travel Ban

It looks like I’ll have to wait until 2028😮‍💨.
