Consider a binary classification task as in Figure~\AMCref{fig:lr_data}, which consists of 14 two-dimensional linearly separable samples (circles corresponds to label $y=1$ and pluses corresponds to label $y=0$). We would like to predict the label $y=1$ of a sample $(x_1, x_2)$ when the following holds true
\[
\prob(y=1|x_1, x_2, w_1, w_2) = rac{1}{1+\exp(-w_1x_1 -w_2x_2)} > 0.5
\]
where $w_1$ and $w_2$ are parameters of the model.
If we obtain the $(w_1, w_2)$ by optimizing the following objective
$$
- \sum_{n=1}^N\log \prob(y_n| x_{n1}, x_{n2}, w_1, w_2) + rac{C}{2} w_2^2

where $C$ is very large, then the decision boundary will be close to which of the following lines?
A. $x_1 + x_2 = 0$

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.
C. (c) Such a learning algorithm is prone to overfitting.
