LARNeXt：基于李代数的端到端残差网络人脸识别
李代数 端到端 残差 网络人脸识别
2023/12/13
Face recognition has always been courted in computer vision and is especially amenable to situations with significant variations between frontal and profile faces. Traditional techniques make great st...

Input design is an important problem for system identification and has been well studied for the classical system identification, i.e., the maximum likelihood/prediction error method. For the emerging...
This paper is concerned with Smith forms of bivariate polynomial matrices. For a bivariate polynomial square matrix with the determinant being the product of two distinct and irreducible univariate po...
极化码的所有保持串行抵消译码不变的仿射自同构（马志明、闫桂英）
