... number of hypotheses that would need to be evaluated in a brute-force search for an optimal hypothesis ˆz is exponential in the sequence length n . We show below that in fact only a few hypotheses ... utility. For a simple class of models, we show that the number of hypotheses whose expected F - score needs to be evaluated is linear in the sequence length and present a framework for e...
