DND: Boosting Large Language Models with Dynamic Nested Depth

ICLR 2026poster

We introduce Dynamic Nested Depth (DND), a novel method that improves performance for off-the-shelf LLMs by selecting critical tokens to reprocess in a nested depth manner. Specifically, at the end of the given transformer layer, DND identifies more critical tokens with a router and feeds them back…

MoBE: Mixture-of-Basis-Experts for Compressing MoE-based LLMs

ICLR 2026poster

The Mixture-of-Experts (MoE) architecture has become a predominant paradigm for scaling large language models (LLMs). Despite offering strong performance and computational efficiency, large MoE-based LLMs like DeepSeek-V3-0324 and Kimi-K2-Instruct present serious challenges due to substantial memory…

Multi-level Causal LLM-based Text-to-Motion Generation with Human Alignment

CVPR 2026

Although progress has been made in LLM-based text-driven motion generation, it still has the limitations of generating fine-grained and semantically consistent motions. These limitations stem from: 1) fine-grained motion quantization errors; 2) mismatches between causal reasoning language and non-ca

Deep Learning Based Topography Aware Gas Source Localization with Mobile Robot

ICRA 2025

Gas source localization in complex environments is critical for applications such as environmental monitoring, industrial safety, and disaster response. Traditional methods often struggle with the challenges posed by a lack of environmental topography integration, especially when interactions betwee

P2 Law: Scaling Law for Post-Training After Model Pruning

ACL 2025long

Pruning has become a widely adopted technique for reducing the hardware requirements of large language models (LLMs). To recover model performance after pruning, post-training is commonly employed to mitigate the resulting performance degradation. While post-training benefits from larger datasets, o…

Streamlining Redundant Layers to Compress Large Language Models

ICLR 2025spotlight

This paper introduces LLM-Streamline, a pioneer work on layer pruning for large language models (LLMs). It is based on the observation that different layers have varying impacts on hidden states, enabling the identification of less important layers to be pruned. LLM-Streamline comprises two parts:…

Sensorized Soft Skin for Dexterous Robotic Hands

ICRA 2024poster

Conventional industrial robots often use two-fingered grippers or suction cups to manipulate objects or interact with the world. Because of their simplified design, they are unable to reproduce the dexterity of human hands when manipulating a wide range of objects. While the control of humanoid hand…

GeoUDF: Surface Reconstruction from 3D Point Clouds via Geometry-guided Distance Representation

ICCV 2023poster

We present a learning-based method, namely GeoUDF, to tackle the long-standing and challenging problem of reconstructing a discrete surface from a sparse point cloud. To be specific, we propose a geometry-guided learning method for UDF and its gradient estimation that explicitly formulates the unsig…

Inspired by Physical Intelligence of an Elephant Trunk: Biomimetic Soft Robot With Pre-Programmable Localized Stiffness

RA-L 2023

Soft robots exhibit promising dexterity and adaptability for manipulation because of their high compliance. However, the existing soft robots with invariant stiffness hardly interact with cluttered environments with varying curvatures. In this study, inspired by the maneuverability of an elephant tr

Explainable Person Re-Identification With Attribute-Guided Metric Distillation

ICCV 2021poster

Despite the great progress of person re-identification (ReID) with the adoption of Convolutional Neural Networks, current ReID models are opaque and only outputs a scalar distance between two persons. There are few methods providing users semantically understandable explanations for why two persons…
