The prediction is the value of $r$ which maximizes the quantity $$| \{ h \in V_t : h (\mathbf{x}_t) = r \} |.$$ This is the number of surviving hypotheses (belonging to $V_t$) which predict $r$ on the current point ($\mathbf{x}_t$). Equivalently, we ask all hypotheses in $V_t$ for their opinion on $\mathbf{x}_t$. If more answer $0$, we predict $0$. If more ...
