TMVA Classification Example Using a Recurrent Neural Network

This is an example of using a RNN in TMVA. We do classification using a toy time dependent data set that is generated when running this example macro

DataSetInfo : [dataset] : Added class "Signal"
: Add Tree sgn of type Signal with 2000 events
DataSetInfo : [dataset] : Added class "Background"
: Add Tree bkg of type Background with 2000 events

: Keras is a high-level API for the Theano and Tensorflow packages.
: This method wraps the training and predictions steps of the Keras
: Python package for TMVA, so that dataloading, preprocessing and
: evaluation can be done within the TMVA system. To use this Keras
: interface, you have to generate a model with Keras first. Then,
: this model can be loaded and trained in TMVA.

: ␛[1m--- Short description:␛[0m
:
: Boosted Decision Trees are a collection of individual decision
: trees which form a multivariate classifier by (weighted) majority
: vote of the individual trees. Consecutive decision trees are
: trained using the original training data set with re-weighted
: events. By default, the AdaBoost method is employed, which gives
: events that were misclassified in the previous tree a larger
: weight in the training of the following tree.
:
: Decision trees are a sequence of binary splits of the data sample
: using a single discriminant variable at a time. A test event
: ending up after the sequence of left-right splits in a final
: ("leaf") node is classified as either signal or background
: depending on the majority type of training events in that node.
:
: ␛[1m--- Performance optimisation:␛[0m
:
: By the nature of the binary splits performed on the individual
: variables, decision trees do not deal well with linear correlations
: between variables (they need to approximate the linear split in
: the two dimensional space by a sequence of splits on the two
: variables individually). Hence decorrelation could be useful
: to optimise the BDT performance.
:
: ␛[1m--- Performance tuning via configuration options:␛[0m
:
: The two most important parameters in the configuration are the
: minimal number of events requested by a leaf node as percentage of the
: number of training events (option "MinNodeSize" replacing the actual number
: of events "nEventsMin" as given in earlier versions
: If this number is too large, detailed features
: in the parameter space are hard to be modelled. If it is too small,
: the risk to overtrain rises and boosting seems to be less effective
: typical values from our current experience for best performance
: are between 0.5(%) and 10(%)
:
: The default minimal number is currently set to
: max(20, (N_training_events / N_variables^2 / 10))
: and can be changed by the user.
:
: The other crucial parameter, the pruning strength ("PruneStrength"),
: is also related to overtraining. It is a regularisation parameter
: that is used when determining after the training which splits
: are considered statistically insignificant and are removed. The
: user is advised to carefully watch the BDT screen output for
: the comparison between efficiencies obtained on the training and
: the independent test sample. They should be equal within statistical
: errors, in order to minimize statistical fluctuations in different samples.
