An Exam for Active Observers

Jiarui Zhang, Muzi Tao, Shangshang Wang +3

Human vision is a closed loop: gaze is continuously redirected by intermediate hypotheses rather than a single snapshot. Decades of psychophysics and cognitive science have argued…

Universal Spectral Tokenization via Self-Supervised Panchromatic Representation Learning

Jeff Shen, Francois Lanusse, Liam Holden Parker +24

Sequential scientific data span many resolutions and domains, and unifying them into a common representation is a key step toward developing foundation models for the sciences. Ast…

AION-1: Omnimodal Foundation Model for Astronomical Sciences

Liam Parker, Francois Lanusse, Jeff Shen +24

While foundation models have shown promise across a variety of fields, astronomy still lacks a unified framework for joint modeling across its highly diverse data modalities. In th…

LLM Unlearning Without an Expert Curated Dataset

Xiaoyuan Zhu, Muru Zhang, Ollie Liu +2

Modern large language models often encode sensitive, harmful, or copyrighted knowledge, raising the need for post-hoc unlearning-the ability to remove specific domains of knowledge…

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…

Resa: Transparent Reasoning Models via SAEs

Shangshang Wang, Julian Asilis, Ömer Faruk Akgül +4

How cost-effectively can we elicit strong reasoning in language models by leveraging their underlying representations? We answer this question with Resa, a family of 1.5B reasoning…

Textual Steering Vectors Can Improve Visual Understanding in Multimodal Large Language Models

Woody Haosheng Gan, Deqing Fu, Julian Asilis +5

Steering methods have emerged as effective and targeted tools for guiding large language models' (LLMs) behavior without modifying their parameters. Multimodal large language model…

METAGENE-1: Metagenomic Foundation Model for Pandemic Monitoring

Ollie Liu, Sami Jaghouar, Johannes Hagemann +4

We pretrain METAGENE-1, a 7-billion-parameter autoregressive transformer model, which we refer to as a metagenomic foundation model, on a novel corpus of diverse metagenomic DNA an…

Euclid: Supercharging Multimodal LLMs with Synthetic High-Fidelity Visual Descriptions

Jiarui Zhang, Ollie Liu, Tianyu Yu +2

Multimodal large language models (MLLMs) have made rapid progress in recent years, yet continue to struggle with low-level visual perception (LLVP) -- particularly the ability to a…

Game-theoretic LLM: Agent Workflow for Negotiation Games

Wenyue Hua, Ollie Liu, Lingyao Li +9

This paper investigates the rationality of large language models (LLMs) in strategic decision-making contexts, specifically within the framework of game theory. We evaluate several…

MatViX: Multimodal Information Extraction from Visually Rich Articles

Ghazal Khalighinejad, Sharon Scott, Ollie Liu +4

Multimodal information extraction (MIE) is crucial for scientific literature, where valuable data is often spread across text, figures, and tables. In materials science, extracting…

IsoBench: Benchmarking Multimodal Foundation Models on Isomorphic Representations

Deqing Fu, Ruohao Guo, Ghazal Khalighinejad +5

Current foundation models exhibit impressive capabilities when prompted either with text only or with both image and text inputs. But do their capabilities change depending on the…

DeLLMa: Decision Making Under Uncertainty with Large Language Models

Ollie Liu, Deqing Fu, Dani Yogatama +1

The potential of large language models (LLMs) as decision support tools is increasingly being explored in fields such as business, engineering, and medicine, which often face chall…

On Retrieval Augmentation and the Limitations of Language Model Training

Ting-Rui Chiang, Xinyan Velocity Yu, Joshua Robinson +3

Augmenting a language model (LM) with -nearest neighbors (NN) retrieval on its training data alone can decrease its perplexity, though the underlying reasons for this remain…

Interpretable Diffusion via Information Decomposition

Xianghao Kong, Ollie Liu, Han Li +2

Denoising diffusion models enable conditional generation and density modeling of complex relationships like images and text. However, the nature of the learned relationships is opa…

Approximating CKY with Transformers

Ghazal Khalighinejad, Ollie Liu, Sam Wiseman

We investigate the ability of transformer models to approximate the CKY algorithm, using them to directly predict a sentence's parse and thus avoid the CKY algorithm's cubic depend…

How does GPT-2 compute greater-than?: Interpreting mathematical abilities in a pre-trained language model

Michael Hanna, Ollie Liu, Alexandre Variengien

Pre-trained language models can be surprisingly adept at tasks they were not explicitly trained on, but how they implement these capabilities is poorly understood. In this paper, w…
