densenet_smplified's Introduction

Description

This is a quick implementation of the DenseNet model described in the paper "Densely Connected Convolutional Networks" by Huang et al. (arXiv)

It has only been tested on the Cifar-10 dataset without data augmentation, but it should work fine on any dataset.

Getting started

The basic model is defined in DenseNet.py.

The scipt cifar10_densenet_classification.py provides an example on how to create and use the model on Cifar-10 classification.

Finally, utils.py contains a few helper functions.

Prerequisites

  • Keras (>= 2) (only tested with Tensorflow backend)
  • numpy (>= 1.13)

Results

Below are the results of running both DenseNet and DenseNet-BC models on Cifar-10 dataset with the same hyperparameters and optimization techniques as in the original paper.

DenseNet (L=40, k=12)

DenseNet_loss DenseNet_accuracy

DenseNet-BC (L=100, k=12)

DenseNet-BC_loss DenseNet-BC_accuracy

TODO

  • Add data augmentation techniques
  • Try different architectures
  • Try other optimizers, eg Adam
  • Try out transfer learning on ImageNet
