Approximate Solomonoff Induction: On the Robustness of Learned Universal Predictors

Qian Li, Shang-Hua Teng

Why large language models trained via log-loss minimization over massive and diverse datasets exhibit broad capabilities and generalizable skills is not yet fully understood. Grau-…

Algorithmic Principles For Multiclass Learning Are Hard To Come By: Limits of Regularization and Proper Learning

Julian Asilis, Shaddin Dughmi, Vatsal Sharan +3

Two of the most fundamental questions in statistical learning theory are the following: which prediction problems are learnable, and how should they be learned? For the former, ele…

Prediction Under Imperfect Compression: A Theory of Approximate MDL

Qian Li, Xinyu Mao, Shang-Hua Teng +1

Minimum Description Length (MDL) formalizes the principle of Occam's razor by optimizing the total description length: . Fo…

Rethinking the Role of Positional Encoding: Sliding-Window Transformers without PE Remain Turing Complete

Qian Li, Xinyu Mao, Shang-Hua Teng

Positional encoding (PE) is widely viewed as necessary for transformers to process ordered sequences: without them, the next-token map appears permutation-invariant in its context…

A Theory of Time-Sensitive Language Generation: Sparse Hallucination Beats Mode Collapse

Atul Ganju, Travis McVoy, Shaddin Dughmi +1

We study language generation in the limit under a global preference ordering on strings, as introduced by Kleinberg and Wei. As is done in previous work, we aim for breadth, but im…

Proper Learnability and the Role of Unlabeled Data

Julian Asilis, Siddartha Devic, Shaddin Dughmi +2

Proper learning refers to the setting in which learners must emit predictors in the underlying hypothesis class , and often leads to learners with simple algorithmic forms (e.g.…

ALPINE: Unveiling the Planning Capability of Autoregressive Learning in Language Models

Siwei Wang, Yifei Shen, Shi Feng +3

Planning is a crucial element of both human intelligence and contemporary large language models (LLMs). In this paper, we initiate a theoretical investigation into the emergence of…
