We present novel reductions from sample compression schemes in multiclass classification, regression, and adversarially robust learning settings to binary sample compression scheme…
Optimal Learners for Realizable Regression: PAC Learning and Online Learning
Idan Attias, Steve Hanneke, Alkis Kalavasis +2
In this work, we aim to characterize the statistical complexity of realizable regression both in the PAC learning setting and the online learning setting. Previous work had establi…
