Convolutional Neural Networks (CNN) for CIFAR-10 Dataset

This repository is about some CNN Architecture's implementations for cifar10.

I just use Keras and Tensorflow to implementate all of these CNN models.

Requirements

• Python (3.5.2)
• Keras (2.0.8)
• tensorflow-gpu (1.3.0)

Architectures and papers

• The first CNN model: LeNet
  • LeNet-5 - Yann LeCun
• Network in Network
  • Network In Network
• Vgg19 Network
  • Very Deep Convolutional Networks for Large-Scale Image Recognition
• Residual Network
  • Deep Residual Learning for Image Recognition
  • Identity Mappings in Deep Residual Networks
• Wide Residual Network
  • Wide Residual Networks
• ResNeXt
  • Aggregated Residual Transformations for Deep Neural Networks
• DenseNet
  • Densely Connected Convolutional Networks
• SENet
  • Squeeze-and-Excitation Networks

Accuracy of all my implementations

network	dropout	preprocess	GPU	params	training time	accuracy(%)
Lecun-Network	-	meanstd	GTX980TI	62k	30 min	76.27

Vgg19-Network	0.5	meanstd	GTX980TI	45M	4 hours	93.53

Wide-resnet 16x8	-	meanstd	GTX1060	11.3M	11 h 32 min	95.14
DenseNet-100x12	-	meanstd	GTX980TI	0.85M	30 h 40 min	95.15
ResNeXt-4x64d	-	meanstd	GTX1080TI	20M	22 h 50 min	95.51
SENet(ResNeXt-4x64d)	-	meanstd	GTX1080	20M	-	-

Now, I fixed some bugs and used 1080TI to retrain all of the following models.

In particular：
Change the batch size according to your GPU's memory.
Modify the learning rate schedule may imporve the results of accuracy!

About ResNeXt & DenseNet

Because I don't have enough machines to train the larger networks.
So I only trained the smallest network described in the paper.
You can see the results in liuzhuang13/DenseNet and prlz77/ResNeXt.pytorch
