Complex SGD and Directional Bias in Reproducing Kernel Hilbert Spaces

★★★★★ significance 2/5

The paper introduces a variant of Stochastic Gradient Descent (SGD) designed for complex-valued parameters. The authors provide convergence guarantees for this complex SGD and demonstrate its efficacy in kernel regression problems using complex reproducing kernel Hilbert spaces.

Why it matters Optimizing complex-valued parameters may unlock more efficient convergence pathways for specialized signal processing and neural architectures.
