Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Structure-preserving machine learning moment closures for the radiative transfer equation
辐射传递方程 结构保持 机器学习 矩闭包
2023/4/24
In this talk, we present our work on structure-preserving machine learning (ML) moment closure models for the radiative transfer equation. Most of the existing ML closure models are not able to guaran...
Optimizing Content-Preserving Projections for Wide-Angle Images
Wide-Angle Images Optimizing Content-Preserving
2016/5/24
Any projection of a 3D scene into a wide-angle image unavoidably
results in distortion. Current projection methods either bend straight
lines in the scene, or locally distort the shapes of scene obj...
Computers have helped revolutionize the commercial world and transformed the lives of the general public through the development of the Internet and mobile technologies like the iPhone. But, practical...

Computer Vision Active Contour Models Optimization Segmentation Networks Topology Roads
2015/12/4
Active contour models have been part of extensive research since their introduction in the late eighties, because their concept of coupling the image data with shape control is a powerful method to de...
Direct Numerical Simulations of a Two-dimensional Viscous Flow in a Shocktube using a Kinetic Energy Preserving Scheme
Direct Numerical Simulations Two-dimensional Viscous Flow Shocktube Kinetic Energy Preserving Scheme
2015/7/3
This paper presents the results of °ow computations done using Jameson's ˉnite volume kinetic energy preserving scheme. Direct numerical simulations were performed in a two dimensional viscous shocktu...
Monotonicity preserving multigrid time stepping schemes for conservation laws
Monotonicity preserving multigrid stepping schemes conservation laws
2015/7/2
In this paper, we propose monotonicity preserving and total variation diminishing (TVD) mul tigrid methods for solving scalar conservation laws. We generalize the upwind-biased residual restriction an...
Privacy-preserving Sanitization in Data Sharing
database social network privacy privacy-preserving data analysis
2014/12/18
In the era of big data, the prospect of analyzing, monitoring and investigating all sources of data starts to stand out in every aspect of our life. The benefit of such practices becomes concrete only...
k-anonymity based framework for privacy preserving data collection in wireless sensor networks
Anonymity Wireless Sensor Networks Data Privacy
2010/10/12
In this paper, k-anonymity notion is adopted to be used in wireless sensor networks (WSN) as a security framework with two levels of privacy. A base level of privacy is provided for the data shared wi...
A Privacy Preserving Attribute Aggregation Model for Federated Identity Managements
A Privacy Preserving Attribute Aggregation Model Federated Identity Managements
2010/9/25
In order to support attribute based access control (ABAC) infederated identity management most existing solutions, such asShibboleth and Cardspace, utilise a model in which a single identityprovider (...
LOCALITY PRESERVING CONSTRAINTS FOR SUPER-RESOLUTION WITH NEIGHBOR EMBEDDING
Super-resolution Neighbor embedding Manifold assumption Locality preserving constraints
2013/7/16
In this paper, we revisit the manifold assumption which has been widely adopted in the learning-based image superresolution. The assumption states that point-pairs from the high-resolution manifold sh...
Low-Resolution Face Recognition via Coupled Locality Preserving Mappings
Coupled locality preserving mappings face recognition low-resolution
2013/7/16
Practical face recognition systems are sometimes confronted with low-resolution face images. Traditional two-step methods solve this problem through employing super-resolution (SR). However, these met...
A General Magnitude-Preserving Boosting Algorithm for Search Ranking
Directed distance function (DDF) magnitude-preserving pairwise-preference
2012/12/3
Traditional boosting algorithms for the ranking problems usually employ the pairwise approach and convert the document rating preference into a binary-value label, like RankBoost. However, such a pair...
