mvpa.mappers.fx

Transform data by applying a function along samples or feature axis.

Functions

absolute_features()	Returns a mapper that converts features into absolute values.
maxofabs_sample()	Returns a mapper that finds max of absolute values of all samples.
mean_group_feature(attrs[, attrfx])	Returns a mapper that computes the mean features of unique feature groups.
mean_group_sample(attrs[, attrfx])	Returns a mapper that computes the mean samples of unique sample groups.
mean_sample([attrfx])	Returns a mapper that computes the mean sample of a dataset.
sumofabs_sample()	Returns a mapper that returns the sum of absolute values of all samples.

Classes

FxMapper(axis, fx[, fxargs, uattrs, attrfx])

Apply a custom transformation to (groups of) samples or features.
