三角分解(LU分解) 在线性代数中, LU分解(LU Decomposition)是矩阵分解的一种,可以将一个矩阵分解为一个单位下三角矩阵和一个上三角矩阵的乘积(有时是它们和一个置换矩阵的乘积)。LU分解主要应用在数值分析中,用来解线性方程、求反矩阵或计算行列式。 本质上,LU分解是高斯消元的一种表达方式。首先,对矩阵A通过初...
# It may or may not throw as the LU decomposition without pivoting # may still succeed for singular matrices try: LU, pivots = fn(A, pivot=pivot) except RuntimeError: return else: LU, pivots = fn(A, pivot=pivot)[:2] self.assertEqual(LU.size(), A.shape) ...
solution: Build a mechanism for a set to act as an observer of its element. Specifically, for an object to be qualified as a set element, it must have an add_observer() method and an implicit notify() method. add_observer() will be called whenever an object is added to the set. no...

Then, a dynamic tensor Bayesian probabilistic decomposition (DTBPD) approach is built by decomposing the dynamic tensor into the outer product of several vectors. Afterward, the Gibbs sampling method is introduced to calibrate the parameters of the DTBPD models. Finally, the real-world traffic ...
拜machine learning 之賜,Eigenvalue decomposition based 的 Principal Components Analysis (PCA) 也變得炙手可熱。 從前只有在線性代線最後幾章帶過的 eigenvalue and eigenvector, 突然有了新的重要性。 Eigenvalue/eigenvector 在控制,信號處理都有非常重要的地位。不過傳統上是從 model matrix 出發 (如 channel...
