• Implement Exploring Randomly Wired Neural Networks for Image Recognition :)

1. Visualize weights
2. Add directory of Drop Connection regularization RandWireNN

1. I added graphing functions for train accuracy, test accuracy, and train loss.
2. I have added a part to report learning time and accuracy. Reporting of the above results can be seen in the reporting folder.

• Experiment with Imagenet dataset.
• To implement Optimzier like the paper.

• As each Epoch passes, we can see that the feature map is formed around the object.

python main.py

• If you want to change hyper-parameters, you can check "python main.py --help"

Options:

• --epochs (int) - number of epochs, (default: 100).
• --p (float) - graph probability, (default: 0.75).
• --c (int) - channel count for each node, (example: 78, 109, 154), (default: 78).
• --k (int) - each node is connected to k nearest neighbors in ring topology, (default: 4).
• --m (int) - number of edges to attach from a new node to existing nodes, (default: 5).
• --graph-mode (str) - kinds of random graph, (exampple: ER, WS, BA), (default: WS).
• --node-num (int) - number of graph node (default n=32).
• --learning-rate (float) - learning rate, (default: 1e-1).
• --model-mode (str) - which network you use, (example: CIFAR10, CIFAR100, SMALL_REGIME, REGULAR_REGIME), (default: CIFAR10).
• --batch-size (int) - batch size, (default: 100).
• --dataset-mode (str) - which dataset you use, (example: CIFAR10, CIFAR100, MNIST), (default: CIFAR10).
• --is-train (bool) - True if training, False if test. (default: True).
• --load-model (bool) - (default: False).

python test.py

• Put the saved model file in the checkpoint folder and saved graph file in the saved_graph folder and type "python test.py".
• If you want to change hyper-parameters, you can check "python test.py --help"
• The model file currently in the checkpoint folder is a model with an accuracy of 92.70%.

Options:

• --p (float) - graph probability, (default: 0.75).
• --c (int) - channel count for each node, (example: 78, 109, 154), (default: 78).
• --k (int) - each node is connected to k nearest neighbors in ring topology, (default: 4).
• --m (int) - number of edges to attach from a new node to existing nodes, (default: 5).
• --graph-mode (str) - kinds of random graph, (exampple: ER, WS, BA), (default: WS).
• --node-num (int) - number of graph node (default n=32).
• --model-mode (str) - which network you use, (example: CIFAR10, CIFAR100, SMALL_REGIME, REGULAR_REGIME), (default: CIFAR10).
• --batch-size (int) - batch size, (default: 100).
• --dataset-mode (str) - which dataset you use, (example: CIFAR10, CIFAR100, MNIST), (default: CIFAR10).
• --is-train (bool) - True if training, False if test. (default: False).

  • Author: Saining Xie Alexander Kirillov Ross Girshick Kaiming He(Facebook AI Research, FAIR)
  • The paper is really awesome.
• Random Graph Generator Module(networkx)
• Visualize Network in Pytorch
• Must have Module, cairosvg
• Separable Convolution Code
• CIFAR benchmark
• CIFAR datasets
• IMAGENET datasets
• Really thank you :)

• Erdos-Renyi (ER) Graph, Watts-Strogatz (WS) Graph and Barabasi-Albert (BA) Graph are all available.
• If you want to visualize the network connection, you can follow the jupyter notebook in visualize_graph directory.
• Label smoothing.
  • In CIFAR-10, The accuracy was 92.00%.
  • But, CIFAR-100, I have seen improvements in CIFAR-100.

• Windows 10, Pycharm community...
• Python 3.7
• Cuda 9.2
• Cudnn 7.1.4
• pytorch 1.0.1
• networkx 2.2
• torchviz 0.0.1
• graphviz 0.10.1
• tqdm 4.31.1
• conda install cairo(If you want to visualize the network, it is a required module.)

• I have presented two graph visualizations. The ONNX module seems to be visualized more intuitively.
  • ONNX module
  • Graphviz module

• It is a picture of the sample small network in the visualize_graph directory.
• When I draw the contents of "Exploring Randomly Wired Neural Networks for Image Recognition" on the network, too many nodes are created. So I tried to draw a small network for visualization.
  • Number of nodes: 7
  • Graph parameters(probability P): 0.4
  • Random seed: 12
  • In_channels: 2
  • Out_channels: 2
• The following figure is a simple example, and the basic RandWired NeuralNetwork Module is provided.
