Show answer & explanation
Correct answer: B. Principle Component Analysis
Explanation
Principal Component Analysis (PCA) is a dimensionality-reduction method: it turns many correlated variables into a few uncorrelated 'principal components' that keep most of the variance. (The paper spells it 'Principle'.)
Principal Component Analysis (PCA) डायमेंशन घटाने की तकनीक है: यह कई सहसंबद्ध वेरिएबल को कुछ असंबद्ध 'प्रिंसिपल कंपोनेंट्स' में बदलती है जिनमें अधिकांश जानकारी बची रहती है।
