Flattened convolutional neural networks (1D convolution modules for Torch nn)

Flattened convolutional neural networks

This package has 1D convolution modules (over channel, in vertical, in horizontal) used in [Flattened Convolutional Neural Networks for Feedforward Acceleration] (http://arxiv.org/abs/1412.5474) where we denote the flattened convolution layer as a sequence of one-dimensional filters across all 3D directions.

Install

Choose both or either of nn/cunn backend packages depending on your computing environment.

luarocks install https://raw.githubusercontent.com/jhjin/flattened-cnn/master/nnconv1d-scm-1.rockspec    # cpu
luarocks install https://raw.githubusercontent.com/jhjin/flattened-cnn/master/cunnconv1d-scm-1.rockspec  # cuda

or use this command if you already cloned this repo.

cd nn-conv1d
luarocks make rocks/nnconv1d-scm-1.rockspec
cd ../cunn-conv1d
luarocks make rocks/cunnconv1d-scm-1.rockspec
