Of course, in the usual case where we only need to consider one model with different reparations, the size of $M$ is fixed and we may use the sum of squared errors (SSE) as well. -Another reasonable cost function is the number of modified transitions. +Another reasonable cost function is the number of modified transitions (NMT). This measure counts the pairs of states $s_1,s_2$ for which the probability of $s_1\to s_2$ differs between $M$ and $M'$. The intuition is that the model is almost correct but may contain human errors, such as off-by-one errors or typos. |
