WebApr 13, 2024 · Background The expectation maximization (EM) algorithm is a common tool for estimating the parameters of Gaussian mixture models (GMM). However, it is highly sensitive to initial value and easily gets trapped in a local optimum. Method To address these problems, a new iterative method of EM initialization (MRIPEM) is proposed in this …

WebGreedy algorithms tend to be made up of five components. These components include: A candidate set from which a solution is created. A selection function, which picks the best candidate that will be added to the solution. A feasibility function. This is used to determine whether a candidate can be used to contribute to a solution.
