Description

Restore tweaked instances to the original scale

Usage

descale.tweakedFeature(tweaked.X, scaled.X)

Arguments

tweaked.X	an object returned by tweak() to be restored.
scaled.X	a scaled matrixa or a scaled data.frame. Usually train set or test set.

Value

a list of

• "original" a data.frame of the same instances before being scalsed.

• "suggest" a data.frame of instances tweakd in original scale.

• "diff" a tibble of (suggest - original)

Examples

## Not run: 
X <- iris[, 1:(ncol(iris)-1)]
scaled.X <- scale(X)
true.y <- iris[, ncol(iris)]

rf.iris <- randomForest(scaled.X, true.y, ntree=30)
es.rf <- set.eSatisfactory(forest.rf, ntree = 30, epsiron = 0.3, resample = TRUE)
tweaked <- tweak(es.rf, newdata= scaled.X, label.from = "spam", label.to = "nonspam",
                 .dopar = TRUE)
dt <- descale.tweakedFeature(tweaked, scaled.X)
