Add Step function

[nuliknol]

Could you add Step function to the list of existing activation functions of the neuron?

Hi @nuliknol , I’d like to work on this issue.
I have experience with neural networks and activation functions, and I believe I can implement the step function and integrate it with the existing neuron options.

Could you please assign this issue to me? Thanks!
