The following are multiple choice questions (with answers) about knowledge and skills in advanced master-level STEM courses.
Consider our standard least-squares problem $$ \operatorname{argmin}_{\mathbf{w}} \mathcal{L}(\mathbf{w})=\operatorname{argmin}_{\mathbf{w}} \frac{1}{2} \sum_{n=1}^{N}\left(y_{n}-\mathbf{x}_{n}^{\top} \mathbf{w}\right)^{2}+\frac{\lambda}{2} \sum_{d=1}^{D} w_{d}^{2} $$ Here, $\left\{\left(\mathbf{x}_{n} y_{n}\right)\right\}_{n=1}^{N}$ is the data. The $N$-length vector of outputs is denoted by $\mathbf{y}$. The $N \times D$ data matrix is called $\mathbf{X}$. It's rows contain the tuples $\mathbf{x}_{n}$. Finally, the parameter vector of length $D$ is called $\mathbf{w}$. (All just like we defined in the course). Mark any of the following formulas that represent an equivalent way of solving this problem.
A. $\operatorname{argmin}_{\boldsymbol{\alpha}} \frac{1}{2} \boldsymbol{\alpha}^{\top}\left(\mathbf{X X}^{\top}+\lambda \mathbf{I}_{N}\right) \boldsymbol{\alpha}-\boldsymbol{\alpha}^{\top} \mathbf{y}$
B. $\operatorname{argmin}_{\mathbf{w}} \sum_{n=1}^{N}\left[1-y_{n} \mathbf{x}_{n}^{\top} \mathbf{w}\right]_{+}+\frac{\lambda}{2}\|\mathbf{w}\|^{2}$. Recall: $[z]_{+}=\max \{0, z\}$
C. $\operatorname{argmin}_{\mathbf{w}}-\log p(\mathbf{y} \mid \mathbf{X}, \mathbf{w}) p(\mathbf{w})$, where $p(\mathbf{w})$ correspond to the density of a $D$-length vector of iid zero-mean Gaussians with variance $1 / \lambda$ and $p(\mathbf{y} \mid \mathbf{X}, \mathbf{w})$ corresponds to the density of a vector of length $N$ of independent Gaussians of mean $\mathbf{x}_{n}^{\top} \mathbf{w}$, variance 1 and observation $\mathbf{y}_{n}$ for component $n$.
D. $\square \operatorname{argmin}_{\mathbf{w}} \frac{1}{2} \sum_{n=1}^{N} \ln \left(1+e^{\mathbf{x}_{n}^{\top} \mathbf{w}}\right)-y_{n} \mathbf{x}_{n}^{\top} \mathbf{w}$
E. $\operatorname{argmin}_{\mathbf{w}} \frac{1}{2}\|\mathbf{y}-\mathbf{X} \mathbf{w}\|^{2}+\frac{\lambda}{2}\|\mathbf{w}\|^{2}$
