(Infinite Data) Assume that your training data $\mathcal{S}=\left\{\left(\mathbf{x}_{n}, y_{n}\right)\right\}$ is iid and comes from a fixed distribution $\mathcal{D}$ that is unknown but is known to have bounded support. Assume that your family of models contains a finite number of elements and that you choose the best such element according to the training data. You then evaluate the risk for this chosen model. Call this the training risk. As $|\mathcal{S}|$ tends to infinity, this training risk converges to the true (according to the distribution $\mathcal{D}$ ) risk of the best model in this family.

Let $\mathbb F$ be a field of cardinality $q$ and let $0<k<n\leq q$ be unspecified integers. As seen in the lecture, we generate a $(n,k,d_{min})$ Reed-Solomon code with the following mapping: $$\mathbb F^k
ightarrow \mathbb F^n ~~,~~ \vec u \mapsto \vec c =(P_{\vec u}(a_1),P_{\vec u}(a_2),\ldots,P_{\vec u}(a_n))$$ for $a_i \in \mathbb F$ all distinct and $P$ a polynomial of degree $k-1$ with coefficient vector $\vec u\in\mathbb F^k$. Now, we construct a $(n,k',d'_{min})$ code $\mathcal C'$ similarly to the above one by assigning $a_1\leftarrow a_2$ while leaving $n,P$ and $a_2,\ldots,a_n$ unchanged. As before, the code is generated by evaluating $P_{\vec u}(a_2,a_2,a_3,\dots,a_n)$ over all possible coefficients vectors $\vec u \in \mathbb F^k$. This is by definition not an RS code, however it is still a well-defined linear block code. True or false: We know for certain that $d'_{min}=d_{min}-1$.

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 $\gamma \in ig( 0, rac{2}{eta}ig)$.

We consider a classification problem on linearly separable data. Our dataset had an outlier---a point that is very far from the other datapoints in distance (and also far from margins in SVM but still correctly classified by the SVM classifier).
We trained the SVM, logistic regression and 1-nearest-neighbour models on this dataset.
We tested trained models on a test set that comes from the same distribution as training set, but doesn't have any outlier points.
For any vector $ v \in \R^D$ let $\| v\|_2 := \sqrt{v_1^2 + \dots + v_D^2}$ denote the Euclidean norm. The hard-margin SVM problem for linearly separable points in $\R^D$ is to minimize the Euclidean norm $\| \wv \|_2$ under some constraints.
What are the additional constraints for this optimization problem?
A. $y_n \ww^ op x_n \geq 1 ~ orall n \in \{1,\cdots,N\}$
B. $\ww^ op x_n \geq 1 ~ orall n \in\{1,\cdots,N\}$
C. $y_n + \ww^ op x_n \geq 1 ~ orall n \in \{1,\cdots,N\}$
D. $ rac{y_n}{\ww^ op x_n }\geq 1 ~ orall n \in \{1,\cdots,N\}$
