R: Multiresolution feature extraction.

extractFDAMultiResFeatures {mlr} | R Documentation

## Multiresolution feature extraction.

### Description

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.

### Usage

    extractFDAMultiResFeatures(res.level = 3L, shift = 0.5, seg.lens = NULL)

### 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).
