Multikernel activation functions: formulation and a case study

no code implementations29 Jan 2019 Simone Scardapane, Elena Nieddu, Donatella Firmani, Paolo Merialdo

In this paper we focus on the kernel activation function (KAF), a recently proposed framework wherein each function is modeled as a one-dimensional kernel model, whose weights are adapted through standard backpropagation-based optimization.
