extractFDAFourier

(<a rd-options="" href="/link/character?package=mlr&version=2.13" data-mini-rdoc="mlr::character">character</a>)
Specifies which transformation of the complex frequency domain
representation should be calculated as a feature representation.
Must be one of &#8220;amplitude&#8221; or &#8220;phase&#8221;.
Default is &#8220;phase&#8221;.

trafo.coeff

The function extracts features from functional data based on the fast fourier
transform. For more details refer to <a rd-options="stats:fft" href="/link/stats%3A%3Afft?package=mlr&version=2.13&to=stats%3Afft" data-mini-rdoc="stats:fft::stats::fft">stats::fft</a>.

Interface to a large number of classification and regression
techniques, including machine-readable parameter descriptions. There is
also an experimental extension for survival analysis, clustering and
general, example-specific cost-sensitive learning. Generic resampling,
including cross-validation, bootstrapping and subsampling. Hyperparameter
tuning with modern optimization techniques, for single- and multi-objective
problems. Filter and wrapper methods for feature selection. Extension of
basic learners with additional operations common in machine learning, also
allowing for easy nested resampling. Most operations can be parallelized.
