Experiment Setup Yes In all experiments we set the covariance matrix for each mixture component as identity matrix Id and define signal-to-noise ratio (SNR) as Rmin. ... For this set of experiments, we use a mixture of 3 Gaussians in 2 dimensions. In both experiments Rmax/Rmin = 1.5. In different settings of π, we apply gradient EM with varying SNR from 1 to 5. For each choice of SNR, we perform 10 independent trials with N = 12, 000 data points.
