The prior probability P [(u, v, w) S[C.sub.k]] can be obtained from a group of training samples that reflect semantic concept S[C.sub.k] and consist of [mathematical expression not reproducible] and its co-occurrence regions to calculate the semantic score of images.

This formulation highlights that computing an LR is generally not free from prior probability assignment at the level of specific scenarios.
Thus, for increasing the prior probability in each recipient with HLA-A*24-B*35-DRB1*04 from 20.3% to 21.3% as the maximum chance of finding at least one HLA-matched donor is required 89 more donors for 50 recipients or 4082 more donors for 100 recipients in a waiting list with that haplotype (figure 3).
Even when the prior probability that the first option is best is 50%, the quality of automatic decisions is 47%, whereas the quality of considered decision is 67%.
