Multiresolution feature extraction.
Source:R/extractFDAFeaturesMethods.R
extractFDAMultiResFeatures.Rd
The function extracts currently the mean of multiple segments of each curve and stacks them as features. The segments length are set in a hierachy way so the features cover different resolution levels.
Arguments
- res.level
(
integer(1)
)
The number of resolution hierachy, each length is divided by a factor of 2.- shift
(
numeric(1)
)
The overlapping proportion when slide the window for one step.- seg.lens
(
integer(1)
)
Curve subsequence lengths. Needs to sum up to the length of the functional.
Value
(data.frame).
