HESSIAN
黑塞矩阵(Hessian Matrix),又译作海森矩阵、海瑟矩阵、海塞矩阵等,是一个多元函数的二阶偏导数构成的方阵,描述了函数的局部曲率。黑塞矩阵最早于19世纪由德国数学家Ludwig Otto Hesse提出,并以其名字命名。黑塞矩阵常用于牛顿法解决优化问题,利用黑塞矩阵可判定多元函数的极值问题。在工程实际问题的优化设计中,所列的目标函数往往很复杂,为了使问题简化,常常将目标函数在某点邻域展开成泰勒多项式来逼近原函数,此时函数在某点泰勒展开式的矩阵形式中会涉及到黑塞矩阵。(Hessian Matrix, is a square matrix of the second order partial derivative of the multivariate function, which describes the local curvature of the function. The Hesse matrix was first proposed by the German mathematician Ludwig Otto Hesse in the 19th century and named after it. Hesse matrix is often used in Newton method to solve the optimization problem, using the black plug matrix to determine the extreme function of the extreme value problem.)
