Regularized Linear Regression
  • regularized both gradient descent and normal equation algorithms for linear regression

calculate min theta for minimizing J theta

Regularization penalize all thetas except theta zero

so the box purple is the regularized derrivative for J theta
and cyan box is derrivative J theta without Regularization

then the separated both zero(?)? and the rest function become one line that shown at the bottom

m often high because of many training set making it really small,  in addition becoming quadratic

next for normal equation....
