        horizont implements a number of topic models. Conventions from scikit-learn_ are
        followed.
        
        The following models are implemented using Gibbs sampling.
        
        - Latent Dirichlet allocation (Blei et al., 2003; Pritchard et al., 2000)
        - (Coming soon) Logistic normal topic model
        - (Coming soon) Dynamic topic model (Blei and Lafferty, 2006)
        
        Getting started
        ---------------
        
        ``horizont.LDA`` implements latent Dirichlet allocation (LDA) using Gibbs
        sampling. The interface follows conventions in scikit-learn_.
        
        .. code-block:: python
        
            >>> import numpy as np
            >>> from horizont import LDA
            >>> X = np.array([[1,1], [2, 1], [3, 1], [4, 1], [5, 8], [6, 1]])
            >>> model = LDA(n_topics=2, random_state=0, n_iter=100)
            >>> doc_topic = model.fit_transform(X)  # estimate of document-topic distributions
            >>> model.components_  # estimate of topic-word distributions
        
        Requirements
        ------------
        
        Python 2.7 or Python 3.3+ is required. The following packages are also required:
        
        - numpy_
        - scipy_
        - scikit-learn_
        - futures (Python 2.7 only)
        
        `GSL <https://www.gnu.org/software/gsl/>`_ is required for random number
        generation inside the Pólya-Gamma random variate generator. On Debian-based
        sytems, GSL may be installed with the command ``sudo apt-get install
        libgsl0-dev``.  horizont looks for GSL headers and libraries in ``/usr/include``
        and ``/usr/lib/`` respectively.
        
        Cython is needed if compiling from source.
