🚨Petej and Vovk have extended Venn–Abers predictors from binary classification to general regression settings
My single-author paper, "Moment Matters: Mean and Variance Causal Graph Discovery from Heteroscedastic Observational Data", has been accepted to #KDD2026 !! 🎊🙌😃😆😁🎉 arxiv.org/abs/2602.23602 I propose an interpretable, moment-driven causal discovery 🤖 See you in Jeju !🏝️😄🇰🇷
🚀🚀🚀New preprint is out🧞♂️🧞♂️🧞♂️ I propose moment-driven causal discovery to uncover complex real-world phenomena🪐 Building on heteroscedastic-noise SCMs, I've developed a Bayesian approach to infer posteriors over both mean and variance causal graphs 🤖 arxiv.org/abs/2602.23602
@0kkus0 Essentially all tools developed for causal inference in RCTs can be adapted to PPI with only minor notational changes. A strong translational treatment and literature review would make that clear and help connect the two literatures rather than separating them.
同じラボ（というと厳密ではないが）のポスドクが条件付き PPI, Prediction-Powered Conditional Inference を提案しています。 arxiv.org/pdf/2603.05575 ある種ファジーなPPIに、この指導教官（若手の結構有名な准教授）の専門がゴリゴリ組み込まれているのが面白いです。これでCATEとかもPPIできそう
Interesting idea, they appear to augment IPW…

Wow this is smart: per-token feedback, no manual reward design, applicable to partial trajectories in principle, all pain points of outcome RL. so curious to see it being applied at scale or combined with existing RL algos
Introducing 💡On-Policy Self-Distillation💡, a simple method that enables LLM to teach itself with dense per-token feedback on its own on-policy generations—achieving 4-8x more token efficiency vs. GRPO and outperforming both GRPO and SFT/Off-Policy Distillation. Key insight:

Jensen's inequality gives the difference between the average value of a convex function φ, and its value at the center, where both “average” and “center” are defined in terms of some distribution p_X. When the function φ is flat, or the distribution is narrow, they agree.
