Interfaces

Shogun is implemented in C++ and offers automatically generated, unified interfaces to Python, Octave, Java / Scala, Ruby, C#, R, Lua. We are currently working on adding more languages including JavaScript, D, and Matlab.

Interface Status
Python mature (no known problems)
Octave mature (no known problems)
Java/Scala stable (no known problems)
Ruby stable (no known problems)
C# stable (no known problems)
R beta (most examples work, static calls unavailable)
Perl pre-alpha (work in progress quality)
JS pre-alpha (work in progress quality)

See our website for examples in all languages.

Platforms

Shogun is supported under GNU/Linux, MacOSX, FreeBSD, and Windows.

The following directories are found in the source distribution. Note that some folders are submodules that can be checked out with git submodule update --init.

  • src - source code, separated into C++ source and interfaces
  • doc - readmes (doc/readme, submodule), Jupyter notebooks, cookbook (API examples), licenses
  • examples - example files for all interfaces
  • data - data sets (submodule, required for examples)

  • Implement heterogeneous (GPU+CPU) dot product computation routines (Deep learning project)

    Implement heterogeneous (GPU+CPU) dot product computation routines (Deep learning project)

    The dot product operation is one of the major building blocks for deep architecture neural networks. The routine implemented in this task should be able to handle batch computation of dot products. For some references see Theano, CUDA, OpenCL, ViennaCL. It is also worth to implement some tests to measure performance and memory specific things.

    Please join the discussion before starting working on any code. We expect to refine the task with further discussion.

    How to commit data to the shogun-data? Need I use another pull request on shogun-data?

  • Add kmeans page to cookbook

    Add kmeans page to cookbook

    • There's no parameter CLabels in class CKMeans, so I can't find a way to use apply_*, eval.evaluate, so as to compare test and training dataset.
    • Though I didn't see why CKMeans cannot have CLabels - we can just label the clusters 1..N.
    • I thought about evaluating the clustering performance by calculating the Euclidean distances between centers of training dataset and test dataset, but there's no handy method for now.
    • I didn't see the difference between dataset fm_train_real.dat and classifier_binary__2d_linear_features_train.datbut I think it doesn't really matter which one to use..?

  • Add meta example features-char-string

    Add meta example features-char-string

    A simple meta example for CStringFeatures.

    I would like to make changes and add output file for an integration test but I am not sure if the current outputs are enough for that. Currently, it stores "max_string_length", "number_of_strings" and "length_of_first_string". I don't think that is possible to practically check all the values of "strings".

    However, if you don't have a better idea I could add eight variables that store the value of the first vector before and after the change to "test".

  • Refactor laplacian

    Refactor laplacian

    @karlnapf take a look at this. I will send the link for the notebook tomorrow.

    Note that the original implementation of LaplacianInferenceMethod in Shogun used log(lu.determinant()) to compute the log_determinant is not numerical stable. (In fact, this implementation do not follow the GPML code)

    Maybe MatrixOperations.h will be merged in Math.h. However, I think in that case the Math.h file need to include the Eigen3 header.

    Another issue is currently I use MatrixXd and VectorXd to pass variables in MatrixOperations.h. maybe SGVector and SGMatrix will be better. (should I use "SGVector &" or "SGVector") I do now know whether passing SGVector to a function is to copy elements in the SGVector.

  • Implement an example of variational approximation for binary GP classification

    Implement an example of variational approximation for binary GP classification

    This task is for the Variational Learning for Recommendations with Big data http://shogun-toolbox.org/page/Events/gsoc2014_ideas#variational_learning

    Our goal is to reproduce a simple example of variational approximation. We will use a GP prior with zero mean and a linear Kernel, and generate synthetic data using a logit likelihood. We will then compute an approximate Gaussian posterior N(m,V) with a restriction that the diagonal of V is 1. Our goal is to find m and V. We will use the KL method of Kuss and Rasmussen, 2005

    I have a demo code in MATLAB here, and the hope is to generate this using Shogun. https://github.com/emtiyaz/VariationalApproxExample

    You need to do the following two main tasks: (1) Write a function similar to ElogLik.m for logit likelihood (2) Interface the optimization in example.m using Shogun's LBFGS implementation.

    Please let us know that you are working on it, and feel free to ask any questions to @karlnapf or me.

    Frustrated with building shogun on RHEL9

    I'm having all sorts of issues building shogun on RHEL9. Is shogun supported on RHEL9?

    Also is there a place where you document the version of supported dependencies? I installed the latest version of eigen3 just to find out it was not compatible with shogun. The gpl stuff is also confusing for anyone building your code for the first time.
