Figure 4From: A Bayesian network approach to feature selection in mass spectrometry dataFeature selection rates. This graph shows the frequency that features were selected as first level features (connected to the disease class node) during 100 cross-validation trials, resulting in 1000 networks. Seven features have been selected in more than 50% of the trials, and these are used for the final classifier. The 76 features not shown were selected in less than 1% of trials.Back to article page
