The EM algorithm is short for Expectation-Maximization algorithm. It is based on an iterative optimization of the centers and widths of the kernels. The aim is to optimize the likelihood that the given data points are generated by a mixture of Gaussians. The numbers next to the Gaussians give the relative importance (amplitude) of each component.
Memtest86 is thorough, stand alone memory test for Intel/AMD x86 architecture
systems. BIOS based memory tests are only a quick check and often miss
failures that are detected by Memtest86.
