	year = {2016}

Dependencies and Installation

We provide two kinds of models -- CNN-based and RNN-based. Barring SketchCNN, the CNN-based models are Caffe-based. The RNN-based models have been obtained using the Lasagne framework. The code has been tested on Ubuntu 14.04 on the following NVIDIA GPUs: TITAN X, NVIDIA K40, NVIDIA K20.

To install Caffe, follow the instructions here
