这些性质类似于通常的半正定矩阵及正定矩阵的性质。2 Positive semi-definite matrices are positive definite if and only if they are nonsingular.正半定矩阵是正定的，当且仅当它们是非奇异矩阵。
LINGO's @POSD function allows one to specify that a matrix of decision variables must be positive semi-definite. The matrix may be either lower triangular, upper triangular or...

Often, the resulting combination matrix is not positive semi- definite (PSD), that is, it has one or more positive eigenvalues and one or more negative eigenvalues. Then, it is not possible to embed the data into a Euclidean space. The combination matrix is not appropriate to train most ...
Similarity based classification methods use positive semi-definite (PSD) similarity matrices. When several data representations (or metrics) are available, they should be combined to build a single similarity matrix. Often the resulting combination is an indefinite matrix and can not be used to train...

正定和半正定这两个词的英文分别是positive definite和positive semi-definite,其中,definite是一个形容词,表示“明确的、确定的”等意思。 初学线性代数的读者可能会被这两个词“唬住”,但正定矩阵和半正定矩阵的定义实际上是很简单的 (不考虑复数构成的矩阵): ...

正定矩阵和半正定矩阵是线性代数中的重要概念，在机器学习模型中广泛运用，如多元正态分布的协方差矩阵要求半正定。定义上，正定矩阵和半正定矩阵描述了实对称矩阵的性质，其中正定矩阵对于所有非零向量的乘积结果恒为正，而半正定矩阵的乘积结果则非负。举例说明，单位矩阵被认为是正定矩阵，因为任何非零...
