Let $f:\R^D\rightarrow\R$ be an $L$-hidden layer multi-layer perceptron (MLP) such that
\[\n\t f(xv)=\sigma_{L+1}\big(wv^\top\sigma_L(Wm_L\sigma_{L-1}(Wm_{L-1}\dots\sigma_1(Wm_1xv)))\big),
\]
with $wv\in\R^{M}$, $Wm_1\in\R^{M\times D}$ and $Wm_\ell\in\R^{M\times M}$ for $\ell=2,\dots, L$, and $\sigma_i$ for $i=1,\dots,L+1$ is an entry-wise activation function. For any MLP $f$ and a classification threshold $\tau$ let $C_{f, \tau}$ be a binary classifier that outputs YES for a given input $xv$ if $f(xv) \leq \tau$ and NO otherwise. \u000bspace{3mm}
Assume $\sigma_{L+1}$ is the element-wise \textbf{sigmoid} function and $C_{f, \frac{1}{2}}$ is able to obtain a high accuracy on a given binary classification task $T$. Let $g$ be the MLP obtained by multiplying the parameters \textbf{in the last layer} of $f$, i.e. $wv$, by 2. Moreover, let $h$ be the MLP obtained by replacing $\sigma_{L+1}$ with element-wise \textbf{ReLU}. Finally, let $q$ be the MLP obtained by doing both of these actions. Which of the following is true?
ReLU(x) = max\{x, 0\} \
Sigmoid(x) = \frac{1}{1 + e^{-x}}
A. $C_{g, \frac{1}{2}}$ may have an accuracy significantly lower than $C_{f, \frac{1}{2}}$ on $T$
B. $C_{h, 0}$ may have an accuracy significantly lower than $C_{f, \frac{1}{2}}$ on $T$
