Multimode resonance transition to collapsed snaking in normal dispersion Kerr resonators: Bright versus dark solitons
Yifan Sun, Stefan Wabnitz, Pedro Parra-Rivas
We study the dynamics of Kerr cavity solitons in the normal dispersion regime, in the presence of an intracavity phase modulation. The associated parabolic potential introduces mul…
Pure quartic three-dimensional spatiotemporal Kerr solitons
Pedro Parra-Rivas, Yifan Sun, Fabio Mangini +3
We analyze the formation of three-dimensional spatiotemporal solitons in waveguides with a parabolic refractive index profile and pure quartic chromatic dispersion. We show, by app…
Whitening-based Contrastive Learning of Sentence Embeddings
Wenjie Zhuo, Yifan Sun, Xiaohan Wang +2
This paper presents a whitening-based contrastive learning method for sentence embedding learning (WhitenedCSE), which combines contrastive learning with a novel shuffled group whi…
Fast Online Node Labeling for Very Large Graphs
Baojian Zhou, Yifan Sun, Reza Babanezhad
This paper studies the online node classification problem under a transductive learning setting. Current methods either invert a graph kernel matrix with runtime…
Feature-compatible Progressive Learning for Video Copy Detection
Wenhao Wang, Yifan Sun, Yi Yang
Video Copy Detection (VCD) has been developed to identify instances of unauthorized or duplicated video content. This paper presents our second place solutions to the Meta AI Video…
Jigsaw: Learning to Assemble Multiple Fractured Objects
Jiaxin Lu, Yifan Sun, Qixing Huang
Automated assembly of 3D fractures is essential in orthopedics, archaeology, and our daily life. This paper presents Jigsaw, a novel framework for assembling physically broken 3D o…
Nonlinear dynamics of dissipative structures in coherently-driven Kerr cavities with a parabolic potential
Yifan Sun, Pedro Parra-Rivas, Mario Ferraro +2
By means of a modified Lugiato-Lefever equation model, we investigate the nonlinear dynamics of dissipative wave structures in coherently-driven Kerr cavities with a parabolic pote…
Dynamics of three-dimensional spatiotemporal solitons in multimode waveguides
Pedro Parra-Rivas, Yifan Sun, Stefan Wabnitz
In this work, we present a detailed study of the dynamics and stability of fundamental spatiotemporal solitons emerging in multimode waveguides with a parabolic transverse profile…
DETR with Additional Global Aggregation for Cross-domain Weakly Supervised Object Detection
Zongheng Tang, Yifan Sun, Si Liu +1
This paper presents a DETR-based method for cross-domain weakly supervised object detection (CDWSOD), aiming at adapting the detector from source to target domain through weak supe…
Exploring Expression-related Self-supervised Learning for Affective Behaviour Analysis
Fanglei Xue, Yifan Sun, Yi Yang
This paper explores an expression-related self-supervised learning (SSL) method (ContraWarping) to perform expression classification in the 5th Affective Behavior Analysis in-the-w…
Unsupervised Facial Expression Representation Learning with Contrastive Local Warping
Fanglei Xue, Yifan Sun, Yi Yang
This paper investigates unsupervised representation learning for facial expression analysis. We think Unsupervised Facial Expression Representation (UFER) deserves exploration and…
A Unified Continual Learning Framework with General Parameter-Efficient Tuning
Qiankun Gao, Chen Zhao, Yifan Sun +4
The "pre-training downstream adaptation" presents both new opportunities and challenges for Continual Learning (CL). Although the recent state-of-the-art in CL is ach…
