IPSM-Bench: A New Intermediate Phase Segmentation Benchmark in Microstructure Images of Zinc-Based Absorbable Biomaterials

IJCAI 2026

Zinc-based alloys are indispensable emerging absorbable metallic biomaterials, and their macroscopic performance is governed by microstructural characteristics. Intermediate phases—key microstructural constituents—are pivotal in regulating mechanical and functional properties. However, intermediate

Origami-Inspired 3-DoF Robotic Joint Design With Pneumatic Actuators

RA-L 2026

Soft pneumatic joints, as the core components of soft robotic manipulators, often face a trade-off between multiple degrees of freedom (DoF) mobility and load capacity. Inspired by the Yoshimura origami pattern, this paper presents a rigid–soft hybrid pneumatic joint. Through spatially ordered place

Segment-Aligned Policy Optimization for Multi-Modal Reasoning

ICML 2026poster

Existing reinforcement learning approaches for Large Language Models typically perform policy optimization at the granularity of individual tokens or entire response sequences. However, such formulations often misalign with the natural step-wise structure of reasoning processes, leading to suboptima…

A Rotary Actuation Strategy for Altering Magnetically Controlled Capsule Endoscope Motion State

RA-L 2025

The magnetically controlled capsule endoscope (MCCE) is an effective tool for the examination of the digestive tract, as it is controlled by an external magnetic field to achieve active movement. Existing rotational actuation strategies are primarily focused on the study of fixed actuation angles, w

DART: Dual-Modal Adaptive Online Prompting and Knowledge Retention for Test-Time Adaptation

AAAI 2024technical

As an up-and-coming area, CLIP-based pre-trained vision-language models can readily facilitate downstream tasks through the zero-shot or few-shot fine-tuning manners. However, they still face critical challenges in test-time generalization due to the shifts between the training and test data distrib…

FineFMPL: Fine-grained Feature Mining Prompt Learning for Few-Shot Class Incremental Learning

IJCAI 2024poster

Few-Shot Class Incremental Learning (FSCIL) aims to continually learn new classes with few training samples without forgetting already learned old classes. Existing FSCIL methods generally fix the backbone network in incremental sessions to achieve a balance between suppressing forgetting old classe…
