Enhancing the functionality of Neural Networks has always been a compelling endeavor in artificial intelligence. The research paper, Discovering Neural Wirings, presents an innovative approach to neural network design, suggesting a more flexible method of establishing connections between channels. This blog will walk you through the process of setting up and running experiments based on this fascinating research.

Understanding Neural Wirings

To better grasp the significance of this research, think of a neural network as a city of roads (connections) between buildings (neurons). Traditionally, these roads are fixed during construction. However, the proposed method allows for the rerouting of roads as the city grows and learns, leading to more efficient traffic (data flow) over time. This flexibility opens doors to enhanced performance and new architectural possibilities in neural networks.

Step-by-Step Setup

Follow these steps to get started with the experiments:

• Clone the Repository: Use the command below to create a local copy of the project.

git clone [repository-url]

• Create a Virtual Environment: To ensure your project dependencies are managed efficiently, set up a virtual environment using Python 3.6.

python -m venv venv
source venv/bin/activate

• Install Requirements: Install necessary dependencies using pip.

pip install -r requirements.txt

• Create Data Directory: Set up a directory named data-dir. If you’re working with ImageNet, create a folder data-dir/imagenet containing the training and validation datasets.

Running Small Scale Experiments

For testing a tiny classifier on CIFAR-10, follow these steps:

• Run one of the experiment files using the command:

bash python runner.py app:appssmall_scale experiment-file --gpus 0 --data-dir data-dir

• You may need multiple GPUs for continuous experiments, using the flag –gpus 0 1.

ImageNet Experiments and Pretrained Models

If you want to train your own model on ImageNet, the command to execute is:

bash python runner.py app:appslarge_scale experiment-file --gpus 0 1 2 3 --data-dir data-dir

To evaluate a pretrained model, use:

bash python runner.py app:appslarge_scale experiment-file --gpus 0 1 --data-dir data-dir --resume path-to-pretrained-model --evaluate

Exploring Other Methods

For those intrigued by other methods of discovering neural wirings, navigate to the apps/medium_scale directory and run:

bash python runner.py app:appsmedium_scale experiment-file --gpus 0 --data-dir data-dir

Troubleshooting

While setting up or running your experiments, you might encounter some hiccups. Here are a few tips:

• Issue with Dependencies: Make sure all required packages are up-to-date. Try running pip install --upgrade -r requirements.txt.
• GPU Allocation Errors: Ensure your GPU is appropriately selected and available for use. Validate your CUDA installation if you’re using GPU acceleration.
• Data Directory Issues: Verify that the data directory exists and is correctly set up with necessary datasets.
