Let $S_{0},S_{1},S_{2},\dots$ be an infinite sequence produced by a source $\mathcal{S}$. All $S_{n}$ take values in $\{0,1\}$, and $S_{n+1}$ depends only on $S_n$, that is, $p_{S_{n+1} | S_0, \dots, S_n}(s_{n+1} | s_0, \dots, s_n) = p_{S_{n+1} | S_n}(s_{n+1} | s_n)$. The probability $p_{S_{n+1}|S_{n}}$ is schematically represented in the graph below: egin{center} ikzset{ state/.style = { draw, circle, minimum size = 20pt, font = ontsize{12}{12}\selectfont, } } egin{tikzpicture}[> = latex]
ode[state] (a) {$0$};
ode[state, right of = a] (b) {$1$}; \path[->] (a) edge[bend left, above] node {$1/2$} (b); \path[->] (a) edge[loop left] node {$ rac{1}{2}$} (); \path[->] (b) edge[bend left, below] node {$1/4$} (a); \path[->] (b) edge[loop right] node {$ rac{3}{4}$} (); \end{tikzpicture} \end{center} For instance, the edge from $0$ to $1$ means that $p_{S_{n+1}|S_{n}}(1|0) = rac{1}{2}$. We also have that $p_{S_0}(0)=1$. True or false: $H(\mathcal{S})= h(1/3)$, where $h$ is the binary entropy.

Which of the following statements is correct?
A. When applying stochastic gradient descent on the objective function $f(\boldsymbol{w}):=\sum_{n=1}^{30}\left\|\boldsymbol{w}-\boldsymbol{x}_{n}\right\|^{2}$ where $\boldsymbol{x}_{n}$ are the datapoints, a stochastic gradient step is roughly $30 \times$ faster than a full gradient step.
B. In practice, it could be good to let your model first overfit your task, and then apply drop-out or other regularization techniques.
C. When applying stochastic gradient descent on the objective function $f(\boldsymbol{w}):=\sum_{n=1}^{30} n \cdot\|\boldsymbol{w}\|^{2}$, a stochastic gradient (for the $n$-th summand) is given by $2 n \cdot \boldsymbol{w}$.
D. The function $f(\boldsymbol{u} ; \boldsymbol{v}):=g\left(\boldsymbol{u} \boldsymbol{v}^{\top}\right)$ is convex over the set of pairs of vectors $(\boldsymbol{u} ; \boldsymbol{v}) \in \mathbb{R}^{2} \times \mathbb{R}^{2}$, when $g: \mathbb{R}^{2 \times 2} \rightarrow \mathbb{R}$ is defined as $g(\boldsymbol{X}):=X_{12}+X_{21}$.

Consider the loss function $L: \R^d o \R$, $L(\wv) = rac{eta}{2}\|\wv\|^2$, where $eta > 0$ is a constant. We run gradient descent on $L$ with a stepsize $\gamma > 0$ starting from some $\wv_0
eq 0$. Which of the statements below is true?
A. Gradient descent converges to the global minimum for any stepsize $\gamma > 0$.
B. Gradient descent with stepsize $\gamma = rac{2}{eta}$ produces iterates that diverge to infinity ($\|\wv_t\| o \infty$ as $t o \infty$).
C. Gradient descent converges in two steps for $\gamma = rac{1}{eta}$ (i.e., $\wv_2$ is the extbf{first} iterate attaining the global minimum of $L$).
D. Gradient descent converges to the global minimum for any stepsize in the interval $\gamma \in ig( 0, rac{2}{eta}ig)$.
