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.
makeExtractFDAFeatMethod(learn, reextract, args = list(), par.set = NULL)
(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.
(function(data, target, col, ...)
)
Function used for reextracting data in predict phase.
Can be equal to learn
.
(list)
Named list of arguments to pass to learn
via ...
.
(ParamSet)
Paramset added to the learner if used in conjunction with a makeExtractFDAFeatsWrapper.
Can be NULL
