Robust three-dimensional high-order solitons and breathers in driven dissipative systems: a Kerr cavity realization
Yifan Sun, Pedro Parra-Rivas, Carles Milian +7
We present a general approach to excite robust dissipative three-dimensional and high-order solitons and breathers in passively driven nonlinear cavities. Our findings are illustra…
Spatiotemporal mode decomposition of ultrashort pulses propagating in graded-index multimode fibers
Mario Zitelli, Vincent Couderc, Mario Ferraro +4
We develop a spatiotemporal mode decomposition technique to study the mode power distribution of ultrashort pulses emerging from long spans of graded-index multimode fiber, for dif…
Semisoft Task Clustering for Multi-Task Learning
Yuzhao Zhang, Yifan Sun
Multi-task learning (MTL) aims to improve the performance of multiple related prediction tasks by leveraging useful information from them. Due to their flexibility and ability to r…
Globular Cluster Ultraluminous X-ray Sources in the Furthest Early-Type Galaxies
E. Thygesen, Y. Sun, J. Huang +5
Ultraluminous X-ray Sources (ULXs) in globular clusters are low mass X-ray binaries that achieve high X-ray luminosities through a currently uncertain accretion mechanism. Using ar…
Generalizable Re-Identification from Videos with Cycle Association
Zhongdao Wang, Zhaopeng Dou, Jingwei Zhang +4
In this paper, we are interested in learning a generalizable person re-identification (re-ID) representation from unlabeled videos. Compared with 1) the popular unsupervised re-ID…
Clustered Federated Learning based on Nonconvex Pairwise Fusion
Xue Yu, Ziyi Liu, Wu Wang +1
This study investigates clustered federated learning (FL), one of the formulations of FL with non-i.i.d. data, where the devices are partitioned into clusters and each cluster opti…
Far Ultra-Violet Insights Into NGC 1399's Globular Cluster Population
Kristen C. Dage, Yifan Sun, Arunav Kundu +2
We investigate archival Hubble Space Telescope ACS/SBC F140LP observations of NGC~1399 to search for evidence of multiple stellar populations in extragalactic globular clusters. En…
Feature-Proxy Transformer for Few-Shot Segmentation
Jian-Wei Zhang, Yifan Sun, Yi Yang +1
Few-shot segmentation (FSS) aims at performing semantic segmentation on novel classes given a few annotated support samples. With a rethink of recent advances, we find that the cur…
Dissipative Kerr solitons, breathers and chimera states in coherently driven passive cavities with parabolic potential
Yifan Sun, Pedro Parra-Rivas, Mario Ferraro +5
We analyze the stability and dynamics of dissipative Kerr solitons in the presence of a parabolic potential. This potential stabilizes oscillatory and chaotic regimes, favoring the…
VL: Leveraging Vision and Vision-language Models into Large-scale Product Retrieval
Wenhao Wang, Yifan Sun, Zongxin Yang +1
Product retrieval is of great importance in the ecommerce domain. This paper introduces our 1st-place solution in eBay eProduct Visual Search Challenge (FGVC9), which is featured f…
UFO: Unified Feature Optimization
Teng Xi, Yifan Sun, Deli Yu +13
This paper proposes a novel Unified Feature Optimization (UFO) paradigm for training and deploying deep models under real-world and large-scale scenarios, which requires a collecti…
Multimode optical fiber beam-by-beam cleanup
Mario Ferraro, Fabio Mangini, Yann Leventoux +8
We introduce and experimentally demonstrate the concept of all-optical beam switching in graded-index multimode optical fibers. Nonlinear coupling between orthogonally polarized se…
Accelerating Frank-Wolfe via Averaging Step Directions
Zhaoyue Chen, Yifan Sun
The Frank-Wolfe method is a popular method in sparse constrained optimization, due to its fast per-iteration complexity. However, the tradeoff is that its worst case global converg…
Bridging the Source-to-target Gap for Cross-domain Person Re-Identification with Intermediate Domains
Yongxing Dai, Yifan Sun, Jun Liu +3
Cross-domain person re-identification (re-ID), such as unsupervised domain adaptive (UDA) re-ID, aims to transfer the identity-discriminative knowledge from the source to the targe…
Results and findings of the 2021 Image Similarity Challenge
Zoë Papakipos, Giorgos Tolias, Tomas Jenicek +11
The 2021 Image Similarity Challenge introduced a dataset to serve as a new benchmark to evaluate recent image copy detection methods. There were 200 participants to the competition…
