The paper asks a simple question: when PFNs are used for causal inference, do their uncertainty estimates actually agree with classical frequentist inference?06 Jul 2026 10:06 +0000at://did:plc:hlmvpsdyr2ymzfvwfaocyniq/app.bsky.feed.post/3mpxtqrfr4k2bhttps://bsky.app/profile/valik-melnychuk.bsky.social/post/3mkz6js5cj22h[1/5] 🇲🇦 Today I’m presenting our paper “Orthogonal Representation Learning for Estimating Causal Quantities” at AISTATS 2026 in Tangier, Morocco; and I’m very happy that it was accepted as an oral.04 May 2026 07:46 +0000at://did:plc:hlmvpsdyr2ymzfvwfaocyniq/app.bsky.feed.post/3mkz6js5cj22hhttps://bsky.app/profile/valik-melnychuk.bsky.social/post/3mk6mqiiur22p[1/5] 🇧🇷 Looking forward to presenting our new paper, “Overlap-Adaptive Regularization for Conditional Average Treatment Effect Estimation,” at ICLR 2026 in Rio de Janeiro. The paper tackles a core challenge in causal ML: estimating treatment effects when overlap is low.23 Apr 2026 18:18 +0000at://did:plc:hlmvpsdyr2ymzfvwfaocyniq/app.bsky.feed.post/3mk6mqiiur22phttps://bsky.app/profile/valik-melnychuk.bsky.social/post/3mk6dplm3g22f[1/4] 🇧🇷 Excited to share our new paper, “GDR-learners: Orthogonal Learning of Generative Models for Potential Outcomes,” which I’ll be presenting at ICLR 2026. The goal: better estimate potential outcome distributions from observational data — not just averages, but the full uncertainty.23 Apr 2026 15:36 +0000at://did:plc:hlmvpsdyr2ymzfvwfaocyniq/app.bsky.feed.post/3mk6dplm3g22fhttps://bsky.app/profile/valik-melnychuk.bsky.social/post/3lmwhtqzybs2n🧵 1/3 Dear friends, I ask everyone again for help! You know the situation in Ukraine is tough at the moment: After the deadly attack on Sumy in Ukraine last Sunday I felt speechless. Yet there is a way to help and even a small contribution might eventually save someone’s life.16 Apr 2025 11:18 +0000at://did:plc:hlmvpsdyr2ymzfvwfaocyniq/app.bsky.feed.post/3lmwhtqzybs2nhttps://bsky.app/profile/valik-melnychuk.bsky.social/post/3ld7gzmkh722b1/n Excited to present our new work, done at the van der Schaar Lab at the Cambridge University together with Mihaela van der Schaar and Stefan Feuerriegel. 📍7008 western ballroom, 11:00-14:00 #NeurIPS202413 Dec 2024 18:46 +0000at://did:plc:hlmvpsdyr2ymzfvwfaocyniq/app.bsky.feed.post/3ld7gzmkh722bhttps://bsky.app/profile/valik-melnychuk.bsky.social/post/3ld2ih4bcfs2v✈️ Attending #NeurlPS2024.
