Nonlinearity Enhanced Adaptive Activation Function

arXiv:2403.19896v1 Announce Type: new
Abstract: A simply implemented activation function with even cubic nonlinearity is introduced that increases the accuracy of neural networks without substantial additional computational resources. This is partially enabled through an apparent tradeoff between convergence and accuracy. The activation function generalizes the standard RELU function by introducing additional degrees of freedom through optimizable parameters that enable the degree of nonlinearity to be adjusted. The associated accuracy enhancement is quantified in the context of the MNIST digit data …
