Axes that matter: PCA with a difference (2503.06707v2)
Published 9 Mar 2025 in q-fin.CP
Abstract: We extend the scope of differential machine learning and introduce a new breed of supervised principal component analysis to reduce dimensionality of Derivatives problems. Applications include the specification and calibration of pricing models, the identification of regression features in least-square Monte-Carlo, and the pre-processing of simulated datasets for (differential) machine learning.
