Implementation of quadrature encoder to train motion features in approximately quadrature relationship.
Example invariant classification script using learned quadrature features.
The script classifies "mnistrot" data, available here, as well as
trained model parameters.
This feature learning script can be used to train the features, for example, using rotating random dot data generated with this script.
The classification script furthermore uses logistic regression,
knn and minimize.
Implementation is in Python / theano.
