PAC Learning with Bandit Feedback: Sharp Sample Complexity in the Realizable Setting
Steve Hanneke, Qinglin Meng, Shay Moran +1
We study the problem of multiclass PAC learning with bandit feedback in the realizable setting. In this framework, there is an unknown data distribution over an instance space $\ma…
On the Learning Curves of Revenue Maximization
Steve Hanneke, Alkis Kalavasis, Shay Moran +1
Learning curves are a fundamental primitive in supervised learning, describing how an algorithm's performance improves with more data and providing a quantitative measure of its ge…
Sample Complexity of Autoregressive Reasoning: Chain-of-Thought vs. End-to-End
Steve Hanneke, Idan Mehalel, Shay Moran
Modern large language models generate text autoregressively, producing tokens one at a time. To study the learnability of such systems, Joshi et al. (COLT 2025) introduced a PAC-le…
An Optimal Sauer Lemma Over -ary Alphabets
Steve Hanneke, Qinglin Meng, Shay Moran +1
The Sauer-Shelah-Perles Lemma is a cornerstone of combinatorics and learning theory, bounding the size of a binary hypothesis class in terms of its Vapnik-Chervonenkis (VC) dimensi…
List Sample Compression and Uniform Convergence
Steve Hanneke, Shay Moran, Tom Waknine
List learning is a variant of supervised classification where the learner outputs multiple plausible labels for each instance rather than just one. We investigate classical princip…
We Should Separate Memorization from Copyright
Adi Haviv, Niva Elkin-Koren, Uri Hacohen +2
The widespread use of foundation models has introduced a new risk factor of copyright issue. This issue is leading to an active, lively and on-going debate amongst the data-science…
