Eigenvalue decomposition and the meaning of singular value decomposition

First, eigenvalue decomposition 1, matrix multiplication before introducing the geometrical meaning of eigenvalue and eigenvector, the geometric meaning of matrix multiplication is introduced. Matrix multiplication corresponds to a transformation, a new vector that transforms any vector into another direction or length. In this process, the original vector mainly occurs in rotation and expansion of the change. If the matrix only has a scaling transformation for some vectors and does not produce a rotational effect, then these vectors are called the eigenvector of the matrix, and the scale of the scaling is the characteristic value. For example:, its corresponding linear transformation is the following form: Because the matrix M is symmetrical ...

"SDN Controller Analysis II" Onos network status statement

Overview The key information maintained by the control plane is the network state. The control plane must aggregate this information and make it available to the application. In addition, in order to maintain scalability and component reuse, applications should be exempt from protocol details, even though network state information is obtained through a specific protocol. The Onos topology of the protocol is implemented by two complementary mechanisms: Network Discovery and configuration. The former uses the network protocol to let Onos identify the location and/or performance of the network elements, and take the initiative to carry out the relevant collection work when the function is enabled. The latter allows applications and operations ...
