From (a), we know $\nabla f(x) = Ax + b$, and hence. Let $x_2, x_3, …, x_n$ be free variables and, respectively, plugging into the original system of equations yields. CS229 Problem Set #1 Solutions 2 The −λ 2 θ Tθ here is what is known as a regularization parameter, which will be discussed in a future lecture, but which we include here because it is needed for Newton’s method to perform well on this task. $\forall x\in \mathbb{R}^m$, $x^TBAB^Tx=(B^Tx)^TA(B^Tx)\geq 0$ since $A$ is PSD. Given that $U$ is orthogonal and $A=U\Lambda U^T$, so $AU=U\Lambda$. Introducing Textbook Solutions. (b) [5 points] Investigate why the training procedure behaves unexpectedly on dataset, .
