The following are multiple choice questions (with answers) about knowledge and skills in advanced master-level STEM courses. Tick the \emph{correct} assertion. In RSA with public key $(e,N)$ and private key $(d,N)$ \ldots A. the key generation requires that $\gcd(e,N) = 1$. B. decryption does not work for some $y \in \mathbb{Z}_N$ for which $\gcd(y,N) \not= 1$. C. if we know $\phi(N)$, the ciphertext $y$ and the public key, we can decrypt $y$. D. in order to decrypt we need to have $e^d \equiv 1 \pmod{N}$. Answer:

The following are multiple choice questions (with answers) about knowledge and skills in advanced master-level STEM courses. Assume we have $N$ training samples $(\xx_1, y_1), \dots, (\xx_N, y_N)$ where for each sample $i \in \{1, \dots, N\}$ we have that $\xx_i \in \R^d$ and $y_i \in \{-1, 1\}$. We want to classify the dataset using the exponential loss $L(\ww) = rac{1}{N} \sum_{i=1}^N \exp (-y_i \xx_i^ op \ww )$ for $\ww \in \R^d$. Which of the following statements is extbf{true}: A. This corresponds to doing logistic regression as seen in class. B. The loss function $L$ is non-convex in $\ww$. C. If I find a vector $\ww^\star$ such that $L(\ww^\star) < 1 / N$, then $\ww^*$ linearly separates my dataset. D. There exists a vector $\ww^\star$ such that $L(\ww^\star) = 0$. E. "None of the statements are true. Answer:
