Its central prescription is unusually concrete: collect choices among three alternatives, not just two, if the goal is to model more individualized preferences in RLHF.","published_at":"2026-10-31","updated_at":"2026-10-31","record_date":"2026-10-31","date_kind":"published_at","topics":["models"],"entities":["MIT EECS","Learning Correlated Reward Models: Statistical Barriers and Opportunities","Random Utility Models","Correlated Probit Model","Yeshwanth Cherapanamjeri","Constantinos Daskalakis","Gabriele Farina","Sobhan Mohammadpour"],"related_patterns":[],"novelty_label":"same_event","what_changed":"Same event as Introducing &Tutor | humans&","prior_refs":["memory:f893f5bd-de0f-8c70-a139-96a20074e845","memory:f5cfb6ab-3b6d-80ca-a355-ad3784f83567"],"source_url":"https://arxiv.org/html/2510.15839v1","source_urls":["https://arxiv.org/html/2510.15839v1"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:learning-correlated-reward-models-statistical-barriers-and-opportunities-d378fd","status":"published","visuals":[],"editor":{"role":"editor","name":"Andrey Reshetnikov","profile":"https://newruntime.com/owner-profile.md","profile_json":"https://newruntime.com/owner-profile.json","same_as":["https://www.linkedin.com/in/reshetnikov1/","https://t.me/lapetuse"]},"routes":{"html":"https://newruntime.com/posts/learning-correlated-reward-models-statistical-barriers-and-opportunities-d378fd/","markdown":"https://newruntime.com/posts/learning-correlated-reward-models-statistical-barriers-and-opportunities-d378fd.md","json":"https://newruntime.com/posts/learning-correlated-reward-models-statistical-barriers-and-opportunities-d378fd.json"},"next_reads":[{"type":"topic","path":"/topics/models/","url":"https://newruntime.com/topics/models/","title":"Models","reason":"Explore the models topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/models.md","json_url":"https://newruntime.com/topics/models.json"},{"type":"collection","path":"/posts/","url":"https://newruntime.com/posts/","title":"Field Notes","reason":"Open the latest editorial analysis.","media_type":"text/html","json_url":"https://newruntime.com/posts.json"},{"type":"collection","path":"/source-ledger.json","url":"https://newruntime.com/source-ledger.json","title":"Source Ledger","reason":"Inspect the public source evidence graph.","media_type":"application/json"}]}
