Co-domain Symmetry for Complex-Valued Deep Learning

no code implementations2 Dec 2021 Utkarsh Singhal, Yifei Xing, Stella X. Yu

We study complex-valued scaling as a type of symmetry natural and unique to complex-valued measurements and representations.

HyperReal: Complex-Valued Layer Functions For Complex-Valued Scaling Invariance

no code implementations1 Jan 2021 Utkarsh Singhal, Yifei Xing, Stella Yu

SurReal complex-valued networks adopt a manifold view of complex numbers and derive a distance metric that is invariant to complex scaling.

Fourier Features Let Networks Learn High Frequency Functions in Low Dimensional Domains

9 code implementations NeurIPS 2020 Matthew Tancik, Pratul P. Srinivasan, Ben Mildenhall, Sara Fridovich-Keil, Nithin Raghavan, Utkarsh Singhal, Ravi Ramamoorthi, Jonathan T. Barron, Ren Ng

We show that passing input points through a simple Fourier feature mapping enables a multilayer perceptron (MLP) to learn high-frequency functions in low-dimensional problem domains.
