setphase

phasename

(character) vector of preprocessors (see ?setpreprocessor) belonging to the phase

preprocessor

(logical) whether phase is missing value imputation

preimpute


Preprocessing phases consist of preprocessing techniques defined with setpreprocessor().
Phases can be defined with setphase() and combined to a grid of combinations with setgrid().


Preprocessing is often the most time-consuming phase in data analysis
and preprocessing transformations interdependent in unexpected
ways. This package helps to make preprocessing faster and more effective. It
provides an S4 framework for creating and evaluating preprocessing combinations
for classification, clustering and outlier detection. The framework supports
adding of user-defined preprocessors and preprocessing phases. Default preprocessors
can be used for low variance removal, missing value imputation, scaling, outlier
removal, noise smoothing, feature selection and class imbalance correction.

setphase: constructor function for defining a preprocessing phase.
