Constructing Bayesian networks for medical diagnosis from incomplete and partially correct statistics. We also introduced an online inference system for predicting functional independence at 3 months and mortality in 1 year of patients with stroke based on the proposed Bayesian network. The output is in the form of a compact graphical model of a probability distribution which assigns a probability to every event of interest. Unlike the filter approach, wrapper methods measure the usefulness of a subset of features by actually training a model on it.

<< Moreover, for some probability threshold p, the Bayesian network can be viewed as inducing the function FNwhich maps each instance e into {0, 1} as follows: FN(e) = 1 if Pr (c | e) ? When a patient was admitted more than twice because of recurrent strokes, only data for the first admission were used for this study. /BaseFont/Times-Bold (1997) 29:13163. (1997) 97:273324. However, patients with comorbid diseases were frequently excluded from the clinical trials, so there are no guidelines and evidence whether to treat or not patients with serious comorbid diseases in real clinical practice.
