Sentence examples for balanced class from inspiring English sources
Finally, using the dataset with missing annotations, predictive models can be derived in cases where no accurate dense dataset is available (not enough data overlap or no well balanced class distribution).
Some of the advantages of Random Forest in a virtual screening setting are: efficient processing of large numbers of examples; capability to handle many input variables; estimate variable importance; by design immune to overfitting and problems due to missing data; and it can predict balanced class populations from unbalanced data sets.
