The DeeBNet (Deep Belief Network) is an object oriented MATLAB toolbox to provide tools for conducting research using Deep Belief Networks. The toolbox has two packages with some classes and functions for managing data and sampling methods and also has some classes to define different RBMs and DBN.

  • DataClasses package has one class to manage training, testing and validation of data. The DataStore class has some useful functions such as normalize and shuffle functions for normalizing and shuffling of data.
  • SamplingClasses package includes the implementation of some different sampling methods. These sampling methods are Gibbs, CD, PCD and FEPCD, where FEPCD is our new sampling method.

The toolbox has also six types of RBM classes.

  • RBM class, is an abstract class that defines all necessary functions (such as training method) and features (like sampler object) in all types of RBMs and therefore , we can't create an object from it. Other RBM classes are inherited from this abstract class.

  • GenerativeRBM

  • DiscriminativeRBM

  • SparseRBM, The SparseRBM can use three different types of sparsity methods where one of them is our new method namely “normal sparse RBM method”.

  • SparseGenerativeRBM

  • SparseDiscriminativeRBM

In addition, some useful codes are implemented. These codes are the functions to read different datasets and different scripts showing how the toolbox can be used in different applications:

  • MNIST for image recognition
  • ISOLET for speech recognition
  • 20 Newsgroups for text categorization

and can be applied to different problems:

  • classification
  • feature extraction
  • data reconstructing
  • noise reduction
  • new data generation
  • ...

More explanations and documentations are in the site.


Changes to previous version:

New features

  • GPU support (about 5 times faster than CPU - test in GPU: NVIDEA GeForce GTX 780 CPU: AMD FX 8150 Eight-Core 3.6 GHz)
  • Cast DBN parameters to single and double data types
  • Sparsity in RBM with three different methods
  • Plotting bases function
  • Classification and feature extraction on 20 Newsgroups datasets
  • Code correction in using back propagation.
  • Runtime and memory code optimization in Normalization and Shuffling
