Quantifying and Optimizing Simplicity via Polynomial Representations

Tianren Zhang, Xiangxin Li, Minghao Xiao +2

Deep networks often exhibit a preference for "simple" solutions, and such a simplicity bias is widely believed to play a key role in generalization. Yet a broadly applicable, quant…

Semantic-Enriched Latent Visual Reasoning

Tianrun Xu, Yue Sun, Qixun Wang +8

Multimodal latent-space reasoning aims to replace explicit thinking with images by performing visual reasoning directly in a compact latent space. However, existing approaches larg…

Reconciling In-Context and In-Weight Learning via Dual Representation Space Encoding

Guanyu Chen, Ruichen Wang, Tianren Zhang +1

In-context learning (ICL) is a valuable capability exhibited by Transformers pretrained on diverse sequence tasks. However, previous studies have observed that ICL often conflicts…

DeFacto: Counterfactual Thinking with Images for Enforcing Evidence-Grounded and Faithful Reasoning

Tianrun Xu, Haoda Jing, Ye Li +6

Recent advances in multimodal language models (MLLMs) have made thinking with images a dominant paradigm for multimodal reasoning. However, existing methods still fail to ensure ev…

Exploring the Hidden Reasoning Process of Large Language Models by Misleading Them

Guanyu Chen, Peiyang Wang, Yizhou Jiang +5

Large language models (LLMs) have been able to perform various forms of reasoning tasks in a wide range of scenarios, but are they truly engaging in task abstraction and rule-based…

When Do Neural Networks Learn World Models?

Tianren Zhang, Guanyu Chen, Feng Chen

Humans develop world models that capture the underlying generation process of data. Whether neural networks can learn similar world models remains an open problem. In this work, we…

A method of supervised learning from conflicting data with hidden contexts

Tianren Zhang, Yizhou Jiang, Feng Chen

Conventional supervised learning assumes a stable input-output relationship. However, this assumption fails in open-ended training settings where the input-output relationship depe…
