Learning Intrinsic Dynamics in Latent World Models

Jiamin Shi, Yuanhong Zhang, Zhiyang Liu +2

Learning intrinsic dynamics---the relationship between actions and their consequences---is essential for world models. However, visual variations unrelated to the underlying contro…

An AI4AI Framework for Visual Token Pruning

Zhen Liu, Wenli Huang, Wei Song +3

Visual-token pruning can substantially reduce the inference cost of multimodal large language models (MLLMs), yet existing methods largely rely on fixed, handcrafted heuristics and…

Improving Auto-Design of Neural PDE Solvers with a Domain-Specific Language

Shengxin Kong, Liwen Xu, Jingwen Fu

Neural PDE solver auto-design is fundamentally a search-space representation problem. In the space of unrestricted Python programs, valid solvers form an extremely sparse subset: m…

Overcoming Statistical Bias in Action-Controllable World Models

Yuhong Shi, Zhenhao Chu, Jie Wei +3

Action-conditioned world models aim to predict how visual environments evolve under an agent's actions. Yet future frames are often highly predictable from visual inertia and recur…

GraphIR: Architecture-Level Search States for LLM-Guided Neural Architecture Evolution

Zhen Liu, Wanqi Zhou, Shuanghao Bai +3

Large language models (LLMs) enable neural architecture search (NAS) directly over executable neural network programs. However, code-level flexibility does not provide the architec…

Overcoming the Weakest-Link Effect in LLM-Driven Program Optimization via Heterogeneous Edit Recombination

Jingwen Fu, Zhen Liu, Yuhan Liu +2

Large language models (LLMs) are increasingly used to solve complex problems by searching over program space, offering a general paradigm for scientific problems that can be natura…

ELVA: Exploring Ranking-Driven Universal Multimodal Retrieval

Yuhan Liu, Pei Fu, Hang Li +8

Leveraging Multimodal Large Language Models (MLLMs) via contrastive learning has become a mainstream paradigm for improving the performance of Universal Multimodal Retrieval (UMR).…

Structured Progressive Knowledge Activation for LLM-Driven Neural Architecture Search

Zhen Liu, Yuhan Liu, Jinjun Wang +3

This paper focuses on a key challenge in Neural Architecture Search (NAS): integrating established architectural knowledge while exploring new designs under expensive evaluations.…

Shaping Schema via Language Representation as the Next Frontier for LLM Intelligence Expanding

Zhiqin Yang, Yuhan Liu, Jingwen Fu +4

Although natural language is the default medium for Large Language Models (LLMs), its limited expressive capacity creates a profound bottleneck for complex problem-solving. While r…

The Essence of Balance for Self-Improving Agents in Vision-and-Language Navigation

Zhen Liu, Yuhan Liu, Jinjun Wang +3

In vision-and-language navigation (VLN), self-improvement from policy-induced experience, using only standard VLN action supervision, critically depends on balancing behavioral div…

Instruction-as-State: Environment-Guided and State-Conditioned Semantic Understanding for Embodied Navigation

Zhen Liu, Yuhan Liu, Jinjun Wang +3

Vision-and-Language Navigation requires agents to follow natural-language instructions in visually changing environments. A central challenge is the dynamic entanglement between la…
