TorchKAN 0.1.1

An easy-to-use PyTorch implementation of the Kolmogorov Arnold Network

TorchKAN: A Simplified KAN Model (Version: 0)

This project demonstrates the training, validation, and quantization of the KAN model using PyTorch with CUDA acceleration. The torchkan model evaluates performance on the MNIST dataset.

Project Status: Under Development

The KAN model has shown promising results amidst various GAMs since the 1980s. This implementation, inspired by various sources, achieves over 97% accuracy with an eval time of 0.6 seconds and the quantised model achieves under 0.55 seconds on the MNIST dataset in 8 epochs on a Ubuntu 22.04 OS with a single Nvidia RTX4090.

As this model is still under study, further exploration into its full capabilities is ongoing.

Prerequisites

Ensure you have the following installed on your system:

• Python (version 3.9 or higher)
• CUDA Toolkit (corresponding to your PyTorch installation's CUDA version)
• cuDNN (compatible with your installed CUDA Toolkit)

Installation

Tested on MacOS and Linux.

1. Clone the Repository

Clone the torchkan repository and set up the project environment:

git clone https://github.com/1ssb/torchkan.git
cd torchkan
pip install -r requirements.txt

Alternately PyPi install as:

pip install torchKAN

2. Configure CUDA environment variables if they are not already set:

export PATH=/usr/local/cuda/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH

3. Configure Weights & Biases (wandb)

To track experiments and model performance with wandb:

1. Set Up wandb Account:

• Sign up or log in at Weights & Biases.
• Find your API key in your account settings.

2. Initialize wandb in Your Project:

Before running the training script, initialize wandb:

wandb login

When prompted, enter your API key. This will link your script executions to your wandb account.

3. Make sure to change the Entity name in the mnist.py file to your username instead of 1ssb

This script will train the model, validate it, and log performance metrics using wandb.
