FiRe: Frequency Reparameterization as a Preconditioner for Periodic Implicit Neural Representations

Harinandan Shukla, Rajarshi Verma, Jitin Singla

Periodic Implicit Neural Representations (INRs) such as SIREN and FINER assign every neuron, the same global frequency, spending the representational budget inefficiently when local signal content varies. We introduce FiRe (Frequency Reparameterization), that accelerates optimiza…Read more
