A simple example is that an eigenvector does not change direction in a transformation:How do we find that vector?The Mathematics Of ItFor a square matrix A, an Eigenvector and Eigenvalue make this equation true:Let us see it in action:...
确认好特征值之后,我们代入(A-\lambda I)x = 0可以得到其特征向量\left[ \begin{matrix} 1 \\1 \end{matrix} \right] \和特征向量x=\left[ \begin{matrix} -1 \\1 \end{matrix} \right] \ 等一下,好像\left[ \begin{matrix} 0&1 \\1& 0 \end{matrix} \right] \的特征向量也是\left[ \...
The meaning of EIGENVECTOR is a nonzero vector that is mapped by a given linear transformation of a vector space onto a vector that is the product of a scalar multiplied by the original vector —called also characteristic vector.

可知:3 和 1 是 A 的特征值, \begin{bmatrix}-\frac{\sqrt{2}}{2}\\ \frac{\sqrt{2}}{2}\end{bmatrix} 是特征值3对应的特征向量, \begin{bmatrix}\frac{\sqrt{2}}{2}\\ \frac{\sqrt{2}}{2}\end{bmatrix} 的特征值 1对应的特征向量。 验算一下 det(A-\lambda I)=(2-\lambda)^...

There are a number of measures that are used to evaluate the performance of machine learning/chemometric models for calibration, i.e. for predicting a continuous value. Most of these come down to reducing the model error, the difference between the reference values and the values predicted (...
