Assuming that $X(4140)$ is the lowest $J^{PC}=1^{++}$ $cs\bar{c}\bar{s}$ tetraquark, we ... More

Dirac monopoles with polar-core vortex induced by spin-orbit coupling in spinor Bose-Einstein condensatesJan 31 2016Aug 18 2016We report Dirac monopoles with polar-core vortex induced by spin-orbit coupling in ferromagnetic Bose-Einstein condensates, which are attached to two nodal vortex lines along the vertical axis. These monopoles are more stable in the time scale of experiment ... More

Fractal Dimension Invariant Filtering and Its CNN-based ImplementationMar 19 2016Mar 17 2017Fractal analysis has been widely used in computer vision, especially in texture image processing and texture analysis. The key concept of fractal-based image model is the fractal dimension, which is invariant to bi-Lipschitz transformation of image, and ... More

Learning Dual Retrieval Module for Semi-supervised Relation ExtractionFeb 20 2019Feb 22 2019Relation extraction is an important task in structuring content of text data, and becomes especially challenging when learning with weak supervision---where only a limited number of labeled sentences are given and a large number of unlabeled sentences ...

Integrating Graph Partitioning and Matching for Trajectory Analysis in Video SurveillanceFeb 02 2015In order to track the moving objects in long range against occlusion, interruption, and background clutter, this paper proposes a unified approach for global trajectory analysis. Instead of the traditional frame-by-frame tracking, our method recovers ... More

Towards Human-Machine Cooperation: Self-supervised Sample Mining for Object DetectionMar 27 2018May 24 2018Though quite challenging, leveraging large-scale unlabeled or partially labeled images in a cost-effective way has increasingly attracted interests for its great importance to computer vision. To tackle this problem, many Active Learning (AL) methods ... More

IRLAS: Inverse Reinforcement Learning for Architecture SearchDec 13 2018Mar 11 2019In this paper, we propose an inverse reinforcement learning method for architecture search (IRLAS), which trains an agent to learn to search network structures that are topologically inspired by human-designed network. Most existing architecture search ... More

Light Fermionic WIMP Dark Matter with Light Scalar MediatorNov 08 2018A light fermionic weakly interacting massive particle (WIMP) dark matter is investigated by studying its minimal renormalizable model, where it requires a scalar mediator to have an interaction between the WIMP and standard model particles. We perform ... More

A Novel Low-cost FPGA-based Real-time Object Tracking SystemApr 16 2018Apr 22 2018In current visual object tracking system, the CPU or GPU-based visual object tracking systems have high computational cost and consume a prohibitive amount of power. Therefore, in this paper, to reduce the computational burden of the Camshift algorithm, ... More

Isospin Symmetry Breaking in ρ\toπγDecayJan 16 2001Apr 05 2002In terms of effective field theory and mixed propagator approach, we show that there is a larger hidden effect of isospin breaking in $\rho^0\to\pi^0\gamma$ decay due to an $\omega$ exchange, $\rho^0\to\omega\to\pi^0\gamma$. The branching ratio is predicted ... More
