Data Mining Methods¶
We define the step to go from the features to a radiomics model, whether it is classification, regression, or survival, as data mining. Within this step, combined model selection and hyperparameter optimization is performed to find the best performing workflow, i.e. combination of models and hyperparameters.
In this part of the documentation, all methods available in the data mining
step are described in the order they occur. The actual single workflow
fitting and scoring is done in WORC.WORC.classification.fitandscore.fit_and_score
,
in which all of these methods are embedded.
Here, we provide a rationale for the methods. For a comprehensive overview of all functions and parameters, please look at the config chapter.
