makeExtractFDAFeatMethod: Constructor for FDA feature extraction methods.

In berndbischl/mlr: Machine Learning in R

Constructor for FDA feature extraction methods.

Description

This can be used to implement custom FDA feature extraction. Takes a learn and a reextract function along with some optional parameters to those as argument.

Usage

makeExtractFDAFeatMethod(learn, reextract, args = list(), par.set = NULL)

Arguments

learn	(⁠function(data, target, col, ...)⁠) Function to learn and extract information on functional column col. Arguments are: data data.frame Data.frame containing matricies with one row per observation of a single functional or time series and one column per meahttps://github.com/mlr-org/mlr/pull/2005/conflict?name=R%252FextractFDAFeatures.R&ancestor_oid=bdc5d882cc86adac456842bebf1a2cf9bb0eb648&base_oid=55d472e23f5c3eb8099607bd9f539034d93e82a4&head_oid=4076800589c60b20acc926e5a545df9f73193b65surement time point. All entries need to be numeric. target (character(1)) Name of the target variable. Default: “NULL”. The variable is only set to be consistent with the API. col (character(1) | numeric(1)) column names or indices, the extraction should be performed on. The function has to return a named list of values.
reextract	(⁠function(data, target, col, ...)⁠) Function used for reextracting data in predict phase. Can be equal to learn.
args	(list) Named list of arguments to pass to learn via ....
par.set	(ParamSet) Paramset added to the learner if used in conjunction with a makeExtractFDAFeatsWrapper. Can be NULL.'
