The matrix L s y m is related to the transition probability matrix of the random walk P by the identity L s y m = I − D 1 / 2 P D − 1 / 2. The small nonzero eigenvalues of L s y m correspond to near- 1 eigenvalues of P. Because p ( t) = p ( 0) P t, the left ...

WebMar 26, 2024 · The Eigenvector is the direction of that line, while the eigenvalue is a number that tells us how the data set is spread out on the line which is an Eigenvector. WebSuppose vectors v and cv have eigenvalues p and q. So Av=pv, A (cv)=q (cv) A (cv)=c (Av). Substitute from the first equation to get A (cv)=c (pv) So from the second equation, q (cv)=c (pv) (qc)v= (cp)v Since v is an eigenvector, it cannot be the 0 vector, so qc=cp, or q=p.
