That is convenient for software interfaces, but it can hide uncertainty exactly where mistakes are expensive. A document router might be unsure between <code>billing</code> and <code>account</code>, yet an <code>argmax</code> still emits one of them.</p> <p><strong>Conformal prediction</strong> offers another interface: return a set of labels sized according to the evidence. Easy inputs can produce one label. Ambiguous inputs can produce several. Under specific assumptions, the procedure also gives a finite-sample coverage guarantee.</p>
