The Velocity Deficit: Initial Energy Injection for Flow Matching
Linze Li, Zong-Wei Hong, Shen Zhang +4
While Flow Matching theoretically guarantees constant-velocity trajectories, we identify a critical breakdown in high-dimensional practice: the Velocity Deficit. We show that the M…
GeoFusion-CAD: Structure-Aware Diffusion with Geometric State Space for Parametric 3D Design
Xiaolei Zhou, Chuangjie Fang, Jie Wu +3
Parametric Computer-Aided Design (CAD) is fundamental to modern 3D modeling, yet existing methods struggle to generate long command sequences, especially under complex geometric an…
Synthesizing Near-Boundary OOD Samples for Out-of-Distribution Detection
Jinglun Li, Kaixun Jiang, Zhaoyu Chen +4
Pre-trained vision-language models have exhibited remarkable abilities in detecting out-of-distribution (OOD) samples. However, some challenging OOD samples, which lie close to in-…
Boosting Generalization with Adaptive Style Techniques for Fingerprint Liveness Detection
Kexin Zhu, Bo Lin, Yang Qiu +3
We introduce a high-performance fingerprint liveness feature extraction technique that secured first place in LivDet 2023 Fingerprint Representation Challenge. Additionally, we dev…
SimpleDG: Simple Domain Generalization Baseline without Bells and Whistles
Zhi Lv, Bo Lin, Siyuan Liang +4
We present a simple domain generalization baseline, which wins second place in both the common context generalization track and the hybrid context generalization track respectively…
