程序代做CS代考 chain flex GMM algorithm Density Estimation with Gaussian Mixture Models
Density Estimation with Gaussian Mixture Models Liang National University Motivation • Inpractice,theGaussiandistributionhaslimitedmodelingcapabilities. • Below is a two-dimensional dataset that cannot be meaningfully represented by a single Gaussian • Wecanusemixturemodelsfordensityestimation. • Mixture models can be used to describe a distribution 𝑝(𝒙) by a convex combination of 𝐾 simple (base) distributions + 𝑝𝒙 =’𝜋(𝑝( 𝒙 ()* 0≤𝜋( […]
