Deep residual networks, or ResNets for short, provided the breakthrough idea of identity mappings in order to enable training of very deep convolutional neural networks. This folder contains an implementation of ResNet for the ImageNet dataset written in TensorFlow.
See the following papers for more background:
Deep Residual Learning for Image Recognition by Kaiming He, Xiangyu Zhang, Shaoqing Ren, and Jian Sun, Dec 2015.
Identity Mappings in Deep Residual Networks by Kaiming He, Xiangyu Zhang, Shaoqing Ren, and Jian Sun, Jul 2016.
Please proceed according to which dataset you would like to train/evaluate on:
You simply need to have the latest version of TensorFlow installed.
First download and extract the CIFAR-10 data from Alex's website, specifying the location with the --data_dir flag. Run the following:
python cifar10_download_and_extract.py
Then to train the model, run the following:
python cifar10_main.py
Use --data_dir to specify the location of the CIFAR-10 data used in the previous step. There are more flag options as described in cifar10_main.py.
To begin, you will need to download the ImageNet dataset and convert it to TFRecord format. Follow along with the Inception guide in order to prepare the dataset.
Once your dataset is ready, you can begin training the model as follows:
python imagenet_main.py --data_dir=/path/to/imagenet
The model will begin training and will automatically evaluate itself on the validation data roughly once per epoch.
Note that there are a number of other options you can specify, including --model_dir to choose where to store the model and --resnet_size to choose the model size (options include ResNet-18 through ResNet-200). See imagenet_main.py for the full list of options.
