Model Objects:
mlnn.m -- Multi-layer neural network
mlcnn.m -- Multi-layer convolutional neural network
rbm.m -- Restricted Boltzmann machine (RBM)
mcrbm.m -- Mean-covariance (3-way Factored) RBM
drbm.m -- Dynamic/conditional RBM
dbn.m -- Deep Belief Network
crbm.m -- Convolutional RBM
ae.m -- Shallow autoencoder

To begin type:
>> startLearning
in the medal directory
To get an idea of how the model objects work, check out the demo script:
>> deepLearningExamples('all')
These examples are by no means optimized, but are for getting familiar with
the code.If you have any questions or bugs, send them my way:
