Consider a learning algorithm that has the property that it depends only very weakly on the input data. E.g., this could be SGD where we choose a very small step size and only run for very few iterations. To go to the extreme, you can imagine a learning algorithm that always outputs the same model irrespective of the training set. Presumably such a learning algorithm will not give us good results. Why is that?
A. (a) Such a learning algorithm typically has a much larger generalization error than training error.
B. (b) Such a learning algorithm typically has a large bias.

Under certain conditions, maximizing the log-likelihood is equivalent to minimizing mean-squared error for linear regression. The mean-squared error can be defined as $\mathcal{L}_{m s e}(\mathbf{w}):=$ $\frac{1}{2 N} \sum_{n=1}^{N}\left(y_{n}-\widetilde{\mathbf{x}}_{n}^{\top} \mathbf{w}\right)^{2}$ and $y_{n}=\widetilde{\mathbf{x}}_{n}^{\top} \mathbf{w}+\varepsilon_{n}$ is assumed for the probabilistic model. Which of following conditions is necessary for the equivalence?
A. The noise parameter $\varepsilon_{n}$ should have a normal distribution.
B. The target variable $y_{n}$ should have a normal distribution.
C. The i.i.d. assumption on the variable $\mathbf{w}$.
D. The conditional probability $p\left(y_{n} \mid \widetilde{\mathbf{x}}_{n}, \mathbf{w}\right)$ should follow a Laplacian distribution.
E. The noise parameter $\varepsilon_{n}$ should have non-zero mean.
