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 $g(\boldsymbol{X}):=X_{12}+X_{21}$.
