name	simple-main-pca
description	Use when working in SIMPLE's src/main/pca subsystem, including PCA, PPCA, complex PPCA, kernel PCA, diffusion maps, and SVD-backed dimensionality-reduction code used in analysis and denoising workflows.

SIMPLE src/main/pca

This folder owns PCA-family methods.

Connections

• Often paired with image stacks, denoising, and analysis workflows
• Likely depends on image/, project/, and numeric utilities

Working Rule

Different PCA variants may share concepts but not assumptions; avoid forcing a single abstraction unless the code already wants it.
