Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Estimation of Common Factors for Microstructure Noise and Effcient Price in a High-frequency Dual Factor Model
高频双因子模型 微结构 噪声公因数 效率价格 估计
2023/4/17
We develop the Double Principal Component Analysis (DPCA) based on a dual factor structure for high-frequency intraday returns contaminated by microstructure noise. The dual factor structure allows a ...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Backpropagation and sensitivity analysis in high-dimensional hyperbolic chaos
高维 双曲混沌 反向传播 敏感性分析
2023/4/26
We devise fast algorithms for computing the linear response, which is the parameter-gradient of long-time statistics of hyperbolic chaotic dynamical systems. The algorithm is in the form of progressiv...

HIGH PERFORMANCE PHOTOGRAMMETRIC PROCESSING ON COMPUTER CLUSTERS
Satellites DEM Digital Model Mosaic Networks Orthoimage Orthorectification Photogrammetry
2014/4/28
Most cpu consuming tasks in photogrammetric processing can be done in parallel. The algorithms take independent bits as input and
produce independent bits as output. The independence of bits comes f...
Approaching Capacity at High-Rates with Iterative Hard-Decision Decoding
Approaching Capacity High-Rates Iterative Hard-Decision Decoding
2012/2/29
A variety of low-density parity-check (LDPC) ensembles have now been observed to approach capacity with message-passing decoding. However, all of them use soft (i.e., non-binary) messages and a poster...
Operations-Based Planning for Placement and Sizing of Energy Storage in a Grid With a High Penetration of Renewables
Operations-Based Planning Energy Storage Grid High Penetration of Renewables
2011/8/16
Abstract: As the penetration level of transmission-scale time-intermittent renewable generation resources increases, control of flexible resources will become important to mitigating the fluctuations ...
A DEFECT CORRECTION METHOD FOR THE EFFECTIVE COMPUTATION OF HIGH-DEGREE FINITE ELEMENT SOLUTIONS
2007/8/7
In this papert a cutting planelnethod is presented for solving the linear BLPP. An optimality criterion for the linear BLPP is derived from two related linear programs constructed by using the complem...

In this paper, the linear mixed finite element method is considered for the biharmonic Dirichlet boundary value problem. Almost optimal error estimates, superconvergence estimates and the derivative e...
A DEFECT CORRECTION METHOD FOR THE EFFECTIVE COMPUTATION OF HIGH-DEGREE FINITE ELEMENT SOLUTIONS
2007/8/7
The high-degree finite element solution of the 2-point boundary value problem: -(p(t)u′(t))′=f(t,u) in (0,1), u(0)=u(1)=0 is considered as a fixed-point of an iterative process using a linear finite e...
It is significant in mathematical problems to decompose a polynomial P(x)intoan irreducible representation as followsP(x)=P1(P2(…(Pn(x))…)).In this paper, we present an effective and efficient algorit...
