Summary difficulty	Written by	Summary

Medium	GrooveSquid.com (original content)	Medium Difficulty Summary The proposed work builds upon a previous study that introduced a feedforward unitary equivariant neural network with three tailored activation functions. While these functions showed desired equivariance properties, they constrained the network’s architecture. This short paper generalizes these activation functions into a single functional form, which represents a broad class of functions, maintains unitary equivariance, and offers greater flexibility for designing equivariant neural networks.
Low	GrooveSquid.com (original content)	Low Difficulty Summary This study makes a feedforward unitary equivariant neural network more versatile by creating one super-activation function that includes all the previous ones. This new activation is good because it keeps the special properties the old ones had and lets you design even better neural networks.
