From Replication to Redesign: Exploring Pairwise Comparisons for LLM-Based Peer Review

NeurIPS 2025poster

The advent of large language models (LLMs) offers unprecedented opportunities to reimagine peer review beyond the constraints of traditional workflows. Despite these opportunities, prior efforts have largely focused on replicating traditional review workflows with LLMs serving as direct substitutes…

Scaling Laws for the Value of Individual Data Points in Machine Learning

ICML 2024poster

Recent works have shown that machine learning models improve at a predictable rate with the amount of training data, leading to scaling laws that describe the relationship between error and dataset size. These scaling laws can help determine a model's training dataset, but they take an aggregate vie…

Understanding Multimodal Contrastive Learning and Incorporating Unpaired Data

AISTATS 2023poster

Language-supervised vision models have recently attracted great attention in computer vision. A common approach to build such models is to use contrastive learning on paired data across the two modalities, as exemplified by Contrastive Language-Image Pre-Training (CLIP). In this paper, (i) we initia…

An Unconstrained Layer-Peeled Perspective on Neural Collapse

ICLR 2022poster

Neural collapse is a highly symmetric geometry of neural networks that emerges during the terminal phase of training, with profound implications on the generalization performance and robustness of the trained networks. To understand how the last-layer features and classifiers exhibit this recently d…
