Nettet26. jul. 2024 · I corrected the mistake in the matrix above now. However, how exactly can I now proceed to find the solution(s), as I now see that the closed form to determine $\textbf{b}$ can not be used? The task is in particular as follows: "Solve the linear regression problem for the set of data described in the introduction. NettetFitting a model via closed-form equations vs. Gradient Descent vs Stochastic Gradient Descent vs Mini-Batch Learning. What is the difference?
