Language Impairment as a Lens onto Large Language Models

Muxuan He, Wang Bill Zhu, Yue Chen +5

Although large language models (LLMs) encode language in highly distributed spaces, they remain vulnerable to focal disruptions---a phenomenon strikingly similar to how localized b…

AutoClimDS: Climate Data Science Agentic AI -- A Knowledge Graph is All You Need

Ahmed Jaber, Wangshu Zhu, Ayon Roy +6

Climate data science remains constrained by fragmented data sources, heterogeneous formats, and steep technical expertise requirements. These barriers slow discovery, limit partici…

Zebra-CoT: A Dataset for Interleaved Vision Language Reasoning

Ang Li, Charles Wang, Deqing Fu +9

Humans often use visual aids, for example diagrams or sketches, when solving complex problems. Training multimodal models to do the same, known as Visual Chain of Thought (Visual C…

PSALM-V: Automating Symbolic Planning in Interactive Visual Environments with Large Language Models

Wang Bill Zhu, Miaosen Chai, Ishika Singh +2

We propose PSALM-V, the first autonomous neuro-symbolic learning system able to induce symbolic action semantics (i.e., pre- and post-conditions) in visual environments through int…

Iterative Formalization and Planning in Partially Observable Environments

Liancheng Gong, Wang Zhu, Jesse Thomason +1

Using LLMs not to predict plans but to formalize an environment into the Planning Domain Definition Language (PDDL) has been shown to improve performance and control. While most ex…

Cancer-Myth: Evaluating Large Language Models on Patient Questions with False Presuppositions

Wang Bill Zhu, Tianqi Chen, Xinyan Velocity Yu +6

Cancer patients are increasingly turning to large language models (LLMs) for medical information, making it critical to assess how well these models handle complex, personalized qu…

Think or Not Think: A Study of Explicit Thinking in Rule-Based Visual Reinforcement Fine-Tuning

Ming Li, Jike Zhong, Shitian Zhao +4

This paper investigates the role of explicit thinking process in rule-based reinforcement fine-tuning (RFT) for MLLMs. We first propose CLS-RL for MLLM image classification, using…

VisualLens: Personalization through Task-Agnostic Visual History

Wang Bill Zhu, Deqing Fu, Kai Sun +8

Existing recommendation systems either rely on user interaction logs, such as online shopping history for shopping recommendations, or focus on text signals. However, item-based hi…

MEGA-Bench: Scaling Multimodal Evaluation to over 500 Real-World Tasks

Jiacheng Chen, Tianhao Liang, Sherman Siu +13

We present MEGA-Bench, an evaluation suite that scales multimodal evaluation to over 500 real-world tasks, to address the highly heterogeneous daily use cases of end users. Our obj…

TLDR: Token-Level Detective Reward Model for Large Vision Language Models

Deqing Fu, Tong Xiao, Rui Wang +5

Although reward models have been successful in improving multimodal large language models, the reward models themselves remain brutal and contain minimal information. Notably, exis…

Language Models can Infer Action Semantics for Symbolic Planners from Environment Feedback

Wang Zhu, Ishika Singh, Robin Jia +1

Symbolic planners can discover a sequence of actions from initial to goal states given expert-defined, domain-specific logical action semantics. Large Language Models (LLMs) can di…

Does VLN Pretraining Work with Nonsensical or Irrelevant Instructions?

Wang Zhu, Ishika Singh, Yuan Huang +2

Data augmentation via back-translation is common when pretraining Vision-and-Language Navigation (VLN) models, even though the generated instructions are noisy. But: does that nois…

Efficient End-to-End Visual Document Understanding with Rationale Distillation

Wang Zhu, Alekh Agarwal, Mandar Joshi +3

Understanding visually situated language requires interpreting complex layouts of textual and visual elements. Pre-processing tools, such as optical character recognition (OCR), ca…

Chain-of-Questions Training with Latent Answers for Robust Multistep Question Answering

Wang Zhu, Jesse Thomason, Robin Jia

We train a language model (LM) to robustly answer multistep questions by generating and answering sub-questions. We propose Chain-of-Questions, a framework that trains a model to g…

Generalization Differences between End-to-End and Neuro-Symbolic Vision-Language Reasoning Systems

Wang Zhu, Jesse Thomason, Robin Jia

For vision-and-language reasoning tasks, both fully connectionist, end-to-end methods and hybrid, neuro-symbolic methods have achieved high in-distribution performance. In which ou…

Navigating Memory Construction by Global Pseudo-Task Simulation for Continual Learning

Yejia Liu, Wang Zhu, Shaolei Ren

Continual learning faces a crucial challenge of catastrophic forgetting. To address this challenge, experience replay (ER) that maintains a tiny subset of samples from previous tas…

Iterative Vision-and-Language Navigation

Jacob Krantz, Shurjo Banerjee, Wang Zhu +4

We present Iterative Vision-and-Language Navigation (IVLN), a paradigm for evaluating language-guided agents navigating in a persistent environment over time. Existing Vision-and-L…

Learning to Generalize Compositionally by Transferring Across Semantic Parsing Tasks

Wang Zhu, Peter Shaw, Tal Linzen +1

Neural network models often generalize poorly to mismatched domains or distributions. In NLP, this issue arises in particular when models are expected to generalize compositionally…
