Web19 ian. 2024 · Returning to principal component analysis, we differentiate L(a1) = a1Σa1– λ(a1ya1– 1) with respect to a1: ∂L ∂a1 = 2Σa1– 2λa1 = 0. Σa1– λa1 = 0. Expressing the above with an identity matrix, I: (Σ– λI)a1 = 0. Which shows λ is an eigenvector of the covariance matrix Σ and a1 is the corresponding eigenvector.
