why intercept is not calculated separately in Lasso_Regression_using_Coordinate_Descent.ipynb

may you clarify
why intercept is not calculated separately in
https://github.com/wiqaaas/youtube/blob/master/Machine_Learning_from_Scratch/Lasso_Regression/Lasso_Regression_using_Coordinate_Descent.ipynb

when it is calculated in
https://github.com/wiqaaas/youtube/blob/master/Machine_Learning_from_Scratch/Ridge_Regression/Ridge_Regression_using_Gradient_Descent.ipynb

[Sandy4321]

same here
https://www.geeksforgeeks.org/implementation-of-lasso-regression-from-scratch-using-python/
db = - 2 * np.sum( self.Y - Y_pred ) / self.m

    # update weights

    self.b = self.b - self.learning_rate * db

[Sandy4321]

here
https://github.com/llSourcell/linear_regression_live/blob/master/demo.py
the same
b_gradient += -(2/N) * (y - ((m_current * x) + b_current))
though
" + b_current"
is mistake

[Sandy4321]

or sorry
(y - ((m_current * x) + b_current))
is ok

in any case in your code
derivative = 2 * np.dot(errors, feature)
from
https://github.com/wiqaaas/youtube/blob/master/Machine_Learning_from_Scratch/Ridge_Regression/Ridge_Regression_using_Gradient_Descent.ipynb

you use multiplication of errors by data
when others not
