A Latent Variable Framework for Scaling Laws in Large Language Models

Peiyao Cai, Chengyu Cui, Felipe Maia Polo +6

We propose a statistical framework built on latent variable modeling for scaling laws of large language models (LLMs). Our work is motivated by the rapid emergence of numerous new…

Bridging Human and LLM Judgments: Understanding and Narrowing the Gap

Felipe Maia Polo, Xinhe Wang, Mikhail Yurochkin +3

Large language models are increasingly used as judges (LLM-as-a-judge) to evaluate model outputs at scale, but their assessments often diverge systematically from human judgments.…

Recurrent Event Analysis with Ordinary Differential Equations

Bo Meng, Weijing Tang, Gongjun Xu +1

This paper introduces a general framework for analyzing recurrent event data by modeling the conditional mean function of the recurrent event process as the solution to an Ordinary…

Denoising Diffused Embeddings: a Generative Approach for Hypergraphs

Shihao Wu, Junyi Yang, Gongjun Xu +1

Hypergraph data, which capture multi-way interactions among entities, are increasingly prevalent in the big data era. Generating new hyperlinks from an observed, usually high-dimen…
