Tensorflow and Keras Implementation of Deep Capsule Neural Networks

Official Implementation of "DeepCaps: Going Deeper with Capsule Networks" paper, will be presented at CVPR 2019.

This code provides deep capsule neural networks (DeepCaps) implemented in Keras with Tensorflow backend. The code supports training the model in multiple GPUs.

The current test error on CIFAR10 = 7.26%.

Usage

step 1 : Install dependencies

conda install -c anaconda tensorflow-gpu=1.13.1
conda install -c anaconda keras-gpu 
conda install -c anaconda scipy=1.2*
conda install -c conda-forge matplotlib
conda install -c conda-forge pillow

step 2 : Clone the repository

git clone https://github.com/brjathu/deepcaps.git
cd deepcaps

Supported Datasets

  • CIFAR10
  • CIFAR100
  • SVHN
  • F-MNIST
  • MNIST
  • tiny-imagenet

Training

If you are training on multiple GPUs change the numGPU parameter in args class in train.py file.

CUDA_VISIBLE_DEVICES=0,1,2,3 python train.py

If you are training on single GPU change the numGPU parameter in args class in train.py file to 1.

CUDA_VISIBLE_DEVICES=0 python train.py or python train.py

To test with several other datasets commnet out the required dataset in the train.py file.

Performance

Dataset Test error
CIFAR10 7.26%
SVHN 2.44%
MNIST 0.28%
FMNIST 5.27%

Download pre-trained models and ensemble test

Download this CIFAR10 - pretrained models and extract the files inside model directory. Then run ensemble.py file.

python ensemble.py
