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.
extractFDAMultiResFeatures(res.level = 3L, shift = 0.5, curve.lens = NULL)(integer(1))
The number of resolution hierachy, each length is divided by a factor of 2.
(numeric(1))
The overlapping proportion when slide the window for one step.
(integer) Curve subsequence lengths. Needs to sum up to the length of the functional.
