Regret Pre-training: Bridging Prior and Posterior Views for Enhanced Knowledge Grounding

Mingkuan Zhao, Xiayu Sun, Wentao Hu +5

Causal language models factorize sequence probabilities using only preceding context, leaving future information unexploited during training despite its availability in the trainin…

MIRROR: A Multi-Agent Framework with Iterative Adaptive Revision and Hierarchical Retrieval for Optimization Modeling in Operations Research

Yifan Shi, Jiayi Wang, Minyi Wu +3

Operations Research (OR) relies on expert-driven modeling--a slow and fragile process ill-suited to novel scenarios. While large language models (LLMs) can automatically translate…

Generation-Augmented Generation: A Plug-and-Play Framework for Private Knowledge Injection in Large Language Models

Rongji Li, Jian Xu, Yi Chen +7

In domains such as materials science, biomedicine, and finance, high-stakes deployment of large language models (LLMs) requires injecting private, domain-specific knowledge that is…

Global PIQA: Evaluating Commonsense Reasoning Across 100+ Languages and Cultures

Tyler A. Chang, Catherine Arnett, Abdelrahman Sadallah +377

To date, there exist almost no culturally-specific evaluation benchmarks for large language models (LLMs) that cover a large number of languages and cultures. In this paper, we pre…

Scaling Clinician-Grade Feature Generation from Clinical Notes with Multi-Agent Language Models

Jiayi Wang, Jacqueline Jil Vallon, Nikhil V. Kotha +8

Developing accurate clinical prediction models is often bottlenecked by the difficulty of deriving meaningful structured features from unstructured EHR notes, a process that tradit…

Multilingual Language Model Pretraining using Machine-translated Data

Jiayi Wang, Yao Lu, Maurice Weber +5

High-resource languages such as English, enables the pretraining of high-quality large language models (LLMs). The same can not be said for most other languages as LLMs still under…

Warmup Generations: A Task-Agnostic Approach for Guiding Sequence-to-Sequence Learning with Unsupervised Initial State Generation

Senyu Li, Zipeng Sun, Jiayi Wang +4

Traditional supervised fine-tuning (SFT) strategies for sequence-to-sequence tasks often train models to directly generate the target output. Recent work has shown that guiding mod…

Multilingual Pretraining Using a Large Corpus Machine-Translated from a Single Source Language

Jiayi Wang, Yao Lu, Maurice Weber +4

English, as a very high-resource language, enables the pretraining of high-quality large language models (LLMs). The same cannot be said for most other languages, as leading LLMs s…

AfriMTE and AfriCOMET: Enhancing COMET to Embrace Under-resourced African Languages

Jiayi Wang, David Ifeoluwa Adelani, Sweta Agrawal +55

Despite the recent progress on scaling multilingual machine translation (MT) to several under-resourced African languages, accurately measuring this progress remains challenging, s…

Strings from the Library of Babel: Random Sampling as a Strong Baseline for Prompt Optimisation

Yao Lu, Jiayi Wang, Raphael Tang +2

Recent prompt optimisation approaches use the generative nature of language models to produce prompts -- even rivaling the performance of human-curated prompts. In this paper, we d…
