Many approaches have been proposed to reduce the influence of measuring errors, among which expectation maximization (EM) …
WebApr 7, 2024 · L(θ) = N ∏ i = 1N(xi; μ, σ), where μ and σ are the mean and covariance. As calculus suggests, the parameters that maximize the likelihood are computed by taking the derivative and setting it to 0. In practice, it is easier to work with the log-likelihood. logℓ(θ) = N ∑ i = 1logN(xi; μ, σ).
