The following are multiple choice questions (with answers) about knowledge and skills in advanced master-level STEM courses.
Let \(A = \{a, b, c, d, ..., z\}\) be the set of lower cased English letters.
Let \(S = \{a, b, ab, cd, ae, xy, ord, ...\}\) be the set of all strings using \(A\) as an alphabet.
Given \(s\in S\), \(N(s)\) is the number of vowels in \(s\).
For example,\(N(algrzqi) = 2\), \(N(bebebe) = 3\).
We say \((s, t)\) belongs to relation \(R\) if \(N(s) \leq N(t)\).
Which of the following statements are true (more than one answer can be correct) ?
A. \(R\) is reflexive.
B. \(R\) is transitive.
C. \(R\) is symmetric.
D. \(R\) is not an equivalence relation.

Let us assume that a kernel $K: \mathcal{X} \times \mathcal{X} \rightarrow \mathbb{R}$ is said to be valid if there exists $k \in \mathbb{N}$ and $\Phi: \mathcal{X} \rightarrow \mathbb{R}^{k}$ such that for all $\left(x, x^{\prime}\right) \in \mathcal{X} \times \mathcal{X}, K\left(x, x^{\prime}\right)=\Phi(x)^{\top} \Phi\left(x^{\prime}\right)$ Which one of the following kernels is not valid ?
A. $\mathcal{X}=\mathbb{N}, K\left(x, x^{\prime}\right)=2$
B. $\mathcal{X}=\mathbb{R}^{d}, K\left(x, x^{\prime}\right)=\left(x^{\top} x^{\prime}\right)^{2}$
C. $\mathcal{X}=\mathbb{R}, K\left(x, x^{\prime}\right)=\cos \left(x-x^{\prime}\right)$
D. All of the proposed kernels are in fact valid.
