摘要：
Today we have learned the Matrix Factorization, and I want to record my study notes. Some kownledge which I have learned before is forgot...（呜呜）1.Terminology单位矩阵：identity matrix特征值：eigenvalues特征向量：eigenvectors矩阵的秩：rank对角矩阵：diagonal matrix对角化矩阵：Diagonalizing a Matrix矩阵分解：matrix factorization奇异值分解：SVD 阅读全文
