from kan import KAN import torch # Create a KAN with 2 inputs, 5 hidden neurons, and 1 output model = KAN(width=[2, 5, 1], grid=5, k=3) # Training follows a standard loop structure # model.train(dataset, opt="LBFGS", steps=20) Use code with caution. Copied to clipboard
: Nodes in a KAN simply sum the incoming signals; they do not have their own activation functions like ReLU or Sigmoid. kan.py

Supports CPU and GPU, though GPU support may require specific configurations in early versions. 5 hidden neurons
The fundamental shift in KANs is the replacement of fixed linear weights with univariate functions.
