Questions & Discussions (about the course or NLP in general)

You're right: in general there is the min(n, max(1, ...)), but here I foccused only the main part : $m-\theta$, then realize that it leads to the same result here since the min (of $D$) is on the diagonal: $min (1, 0, 1) = min (0, 1)$.
Sorry for confusion if that specific case was unclear.
