Gaussian Mixture Models: What are they & when to use?

WebLet us partition the vector into two components: x = x 1 x 2 : We partition the mean vector and covariance matrix in the same way: = 1 2 = 11 12 21 22 : Now the marginal … Web31 Jul 2024 · Mixtures of Gaussians. The probability density function of is defined as where is a vector of means, and is an covariance matrix. ... Thus, the RD data were partitioned into two clusters using the k-means method, denoted as PC1 and PC2, as shown in Figure 6(a). The cluster means for PC1 were 1.343257 and −1.210463, whereas those of PC2 were ... WebThe covariance in (2.88) is expressed in terms of the partitioned precision matrix given by (2.69). We can rewrite this in terms of the corresponding partitioning of the covariance matrix given by (2.67), as we did for the conditional distribution. These partitioned matrices are related by −1 Λaa Λab Σaa Σab = (2.90) pit and pub specials
