Uchanganuzi wa vipengele mkuu thabiti (Robust Principal Component Analysis - RPCA)

Uchanganuzi wa vipengele mkuu thabiti (RPCA) ni mbinu ya upunguzaji wa vipimo inayotoa vipengele vinavyotegemewa wakati data zinapochafuliwa na vipengele vya nje (outliers) na kelele. Ilianzishwa na Candès, Li, Ma na Wright (2011), na kuendelezwa katika mbinu ya ROBPCA ya Hubert, Rousseeuw na Vanden Branden (2005), inatenganisha tumbo la data kuwa sehemu safi yenye kiwango cha chini (low-rank) na sehemu ya nje yenye kuenea (sparse).
