Task: Question Answering
Input (English): Which of the following is false?
(A)The following fully connected network without activation functions is linear: $g_3(g_2(g_1(x)))$, where $g_i(x) = W_i x$ and $W_i$ are matrices. (B)Leaky ReLU $\max\{0.01x,x\}$ is convex. (C)A combination of ReLUs such as $ReLU(x) - ReLU(x-1)$ is convex. (D)The loss $\log \sigma(x)= -\log(1+e^{-x})$ is concave
