- xthestreams 6y agoIntroducing linear regression with gradient descent can also be really confusing for a newcomer. Gradient descent solves a problem (nonlinear optimization) which does not exist here.
- leovailati 6y agoI agree. What is the purpose of applying gradient descent to a linear regression problem? I mean, the pseudo inverse _is_ a closed form solution! Is it maybe more efficient for very large problems? I just don't get it.
