That is, all projections are transformations, but not all transformations are projections. Projections often come up in linear algebra and functions between real numbers, in which a projection means that the dimensionality of the space is reduced.
Web得到 p=ax=a\frac {a^Tb} {a^Ta} ，进一步再把这个投影写成 投影矩阵 (Projection Matrix) 的形式： p=Pb ，其中 P 是矩阵，那么： p=ax=\frac {aa^Tb} {a^Ta}\\ P=\frac {aa^T} {a^Ta} 关键性质大概有三条： Rank (P)=1 。 想想 P=\frac {aa^T} {a^Ta} 的 column space，分母是个 scalar，分子是个矩阵并且每一列是 a 向量本身的常数倍，Rank 是 1 没毛病。 所以任何 … WebJun 20, 2024 · 三个皮匠报告网每日会更新大量报告，包括行业研究报告、市场调研报告、行业分析报告、外文报告、会议报告、招股书、白皮书、世界500强企业分析报告以及券商报告等内容的更新，通过行业分析栏目，大家可以快速找到各大行业分析研究报告等内容。
