BinaryNet: Training Deep Neural Networks with Weights and Activations Constrained to +1 or -1

  title={BinaryNet: Training Deep Neural Networks with Weights and Activations Constrained to +1 or -1},
  author={Matthieu Courbariaux and Yoshua Bengio},
We introduce BinaryNet, a method which trains DNNs with binary weights and activations when computing parameters’ gradient. We show that it is possible to train a Multi Layer Perceptron (MLP) on MNIST and ConvNets on CIFAR-10 and SVHN with BinaryNet and achieve nearly state-of-the-art results. At run-time, BinaryNet drastically reduces memory usage and replaces most multiplications by 1-bit exclusive-not-or (XNOR) operations, which might have a big impact on both general-purpose and dedicated… CONTINUE READING
