        <![CDATA[
DeepMicro is a deep representation learning framework exploiting various autoencoders 
to learn robust low-dimensional representations from high-dimensional data and training
classification models based on the learned representation.

======================================
Option 1) Only representation learning
====================================== 

The representation learning does not require class labels and can be learned from the features alone. 
The wrapper allows to explore multiple paramertes (i.e. different modes to
generate the features, please refer to the publication for details), for each 
added parameter the encoded features are generated. Those features can then be passed to subsequent ML tools,
such as `Ensemble methods for classification and regression` or `Split Dataset into training and test subsets`

=====================================================
Option 2)  Representation learning and classification
=====================================================

The tool itself can also evaluate the performance of the generated representation learning for different
classifiers internally using 5 fold CV. The wrapper allows to explore multiple paramertes and clfs.
Each parameter run will be stored as a line to the result file. If this option is chosen the latent representation is not
exported as output. To create the latent representation of the complete feature set, run the tool again
with the same parameters using the `Only representation learning` option.
The header of the result file is: 

'{Encoding}_{classifier}, AUC, ACC, Recall, Precision, F1_score, time-end, runtime(sec), classfication time(sec), best hyper-parameter'

The overall schema of the tool is shown in:
