CrossDomainAdjust: Lambda-Controlled Cross-Domain Feature Adjustment
Provides cross-domain feature adjustment methods for biological
and other tabular data. Domain labels define group centroids, and singular
value decomposition of their offsets from a common anchor estimates a
domain-shift subspace. An orthogonal projection removes a user-controlled
fraction of each sample's component in that subspace. A correction strength
of zero preserves the input; a strength of one removes the entire learned
subspace component. Intermediate values provide partial correction. The
fitted transformation can be applied to new samples without refitting.
