OpenThoughts-Agent: Data Recipes for Agentic Models

Negin Raoof, Richard Zhuang, Marianna Nezhurina +47

Agentic language models dramatically expand the applications of AI yet little is publicly known about how to curate training data for broadly capable agents. Existing open efforts…

TERMS-Bench: Diagnosing LLM Negotiation Agents Beyond Deal Rate

Erica Zhang, Fangzhao Zhang, Aneesh Pappu +5

Negotiation is a central mechanism of economic exchange, shaping markets, procurement, labor agreements, and resource allocation. It is also a canonical testbed for agentic languag…

Optimizer-Induced Mode Connectivity: From AdamW to Muon

Fangzhao Zhang, Sungyoon Kim, Erica Zhang +2

Mode connectivity has been widely studied, yet the role of the optimizer remains underexplored. We revisit it through optimizer-induced implicit regularization, asking how connecti…

Learning When to Trust LLM Priors: A Validated Framework for Semantic Prior Integration

Erica Zhang, Naomi Sagan, Danny Tse +3

Large language models (LLMs) encode rich semantic knowledge that can be useful for supervised learning, but their outputs are unreliable as statistical priors: they may be noisy, m…

LLM-Lasso: A Robust Framework for Domain-Informed Feature Selection and Regularization

Erica Zhang, Ryunosuke Goto, Naomi Sagan +7

We introduce LLM-Lasso, a novel framework that leverages large language models (LLMs) to guide feature selection in Lasso regression. Unlike traditional methods that rely…

Active Learning of Deep Neural Networks via Gradient-Free Cutting Planes

Erica Zhang, Fangzhao Zhang, Mert Pilanci

Active learning methods aim to improve sample complexity in machine learning. In this work, we investigate an active learning scheme via a novel gradient-free cutting-plane trainin…
