Weak-to-Strong Generalization is Nearly Inevitable (in Linear Models)
Scott Geng, Dutch Hansen, Jerry Li
Weak-to-strong generalization is a phenomenon in post-training whereby a strong student model, when finetuned solely with feedback from a weaker teacher, can not only surpass the t…
Semi-Random Graphs, Robust Asymmetry, and Reconstruction
Julian Asilis, Xi Chen, Dutch Hansen +1
The Graph Reconstruction Conjecture famously posits that any undirected graph on at least three vertices is determined up to isomorphism by its family of (unlabeled) induced subgra…
Auditability and the Landscape of Distance to Multicalibration
Nathan Derhake, Siddartha Devic, Dutch Hansen +2
Calibration is a critical property for establishing the trustworthiness of predictors that provide uncertainty estimates. Multicalibration is a strengthening of calibration which r…
When is Multicalibration Post-Processing Necessary?
Dutch Hansen, Siddartha Devic, Preetum Nakkiran +1
Calibration is a well-studied property of predictors which guarantees meaningful uncertainty estimates. Multicalibration is a related notion -- originating in algorithmic fairness…
