Swap sample and feature axes.
This mapper swaps the sample axis (first axis) and feature axis (second axis) of a dataset (additional axes in multi-dimensional datasets are left untouched). Both, sample and feature attribute collections are also swapped accordingly. Neither dataset samples, not attribute collections are copied. Reverse mapping is supported as well. This mapper does not require training and a single instance can be used on different datasets without problems.

Methods
forward(data) | Map data from input to output space. |
forward1(data) | Wrapper method to map single samples. |
generate(ds) | Yield processing results. |
get_postproc() | Returns the post-processing node or None. |
get_space() | Query the processing space name of this node. |
reset() | |
reverse(data) | Reverse-map data from output back into input space. |
reverse1(data) | Wrapper method to map single samples. |
set_postproc(node) | Assigns a post-processing node |
set_space(name) | Set the processing space name of this node. |
train(ds) | The default implementation calls _pretrain(), _train(), and finally _posttrain(). |
untrain() | Reverts changes in the state of this node caused by previous training |
