The Central Limit Theorem states that, given certain conditions, the distribution of the mean of a large sample of independent and identically distributed (i.i.d.) random variables will approximate a normal distribution, even if the original variables are not normally distributed. In other words, as the sample size (n) increases, the distribution of the sample mean … Read more

The Singular Value Decomposition (SVD) is a factorization of a matrix A into three matrices: The SVD can be written as: A = U Σ V* The singular values in Σ are non-negative and represent the importance of each column of A. The columns of U and V are orthonormal, meaning they have length 1 … Read more

Multimode fiber (MMF) is a kind of optical fiber mostly used in communication over short distance. Multimode fiber optic cable has a larger core, about 50 or 62.5 microns that enables multiple light modes to be propagated.
