Frequency–Time Domain Alignment for Cross-Subject Time-Series Classification Under Distribution Shift

FTDA (Frequency–Time Domain Alignment), an unsupervised domain-adaptation method that processes raw signals and their FFT-magnitude spectra through a dual-branch encoder, combines a Gradient-Reversal adversarial loss on the joint feature with a Multi-Kernel MMD on the frequency branch and applies a symmetric-KL time–fr...
