Eigenvector and Eigenvalues crash course

Linear Transformation

  • Linear transformation of X with Y is X . Y
  • Transformation matrix is used to change direction, magnitude and sometimes both of the matrix

Eigenvector and Eigenvalue

  • As we look deeper into machine learning concepts, ability to transform a vector by only a factoring scalor is very useful
  • Eigenvectors, is a scalar multiple of itself when multiplied by transformation matrix
  • Eigenvalue, is the scalar multiple of eigenvector
  • The first step is to find eigenvalues
  • The vector only change in magnitude not in direction is represented by 1A . x̅ = λ . x̅, where A is the transformation matrix, x̅ is the eigenvector and λ is the eigenvalue
