Question 1: Select all that apply

A single threshold perceptron outputs 1 when $\sum_i w_i x_i - w_T > 0$ and 0 otherwise. Which of these functions can it compute, for suitable weights? Select all that apply.

$A < B$ for real-valued inputs $A, B$ 1
$A \oplus B$ (exclusive or) for Boolean inputs2
$|A - B| < E$ for real-valued inputs $A, B, E$ 3
$A \rightarrow B$ (that is, $\neg A \lor B$ ) for Boolean inputs $A, B \in \{0, 1\}$ 4
