%description
    CNTK, the Computational Network Toolkit by Microsoft Research, is a
    unified deep-learning toolkit that describes neural networks as a
    series of computational steps via a directed graph. In this directed
    graph, leaf nodes represent input values or network parameters,
    while other nodes represent matrix operations upon their inputs.
    CNTK allows to easily realize and combine popular model types such
    as feed-forward DNNs, convolutional nets (CNNs), and recurrent
    networks (RNNs/LSTMs). It implements stochastic gradient descent
    (SGD, error backpropagation) learning with automatic differentiation
    and parallelization across multiple GPUs and servers.
