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.
Table 1: The prior probability P([H.sub.0]) of the year from 2007 to 2011.
The client based solutions including more recent work such as [2, 3, 6] perform on users' devices and generate k - 1 dummies in a local manner, in which process certain side information is adopted, for instance, the prior probability of each query content.
This formulation highlights that computing an LR is generally not free from prior probability assignment at the level of specific scenarios.
Then, the prior probability of a landslide surge occurring and the conditional probability of the dam overtopping due to the landslide surge can be computed according to the simulation results.
Variables with higher prior probability show a slight increase in the posterior selection rate.
This medical knowledge base includes mainly 11 kinds of respiratory diseases and 380 three-layer model pieces of information, including prior probability knowledge and specificity value.
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%.
