NON-SQUARE BLIND SOURCE SEPARATION UNDER COHERENT NOISE BY BEAMFORMING AND TIME-FREQUENCY MASKING
NON-SQUARE BLIND SOURCE SEPARATION COHERENT NOISE BY BEAMFORMING TIME-FREQUENCY MASKING
2015/9/29
To be applicable in realistic scenarios, blind source separation approaches should deal evenly with non-square cases and the presence of noise. We consider an additive noisemixing model with an arbitr...

Coherent风险度量 现金流 表示定理
2013/10/19
本文讨论现金流情形下的Coherent风险度量的表示定理,给出了初始时刻的Coherent风险度量的表示定理,还给出了现金流期内任一时刻t的Ft-Coherent风险度量的表示定理.
In this paper we indicate a natural generalization of the notion of the coherent risk measure in some partially ordered normed linear space E, according to the remark that was first made in [9] about ...

Braid group actions on derived categories of coherent sheaves
Braid group derived categories coherent sheaves
2010/10/29
This paper gives a construction of braid group actions on the derived category of coherent sheaves on a variety $X$. The motivation for this is Kontsevich's homological mirror conjecture, together wit...
