Abstract
The expectation maximization algorithm arises in many computational biology applications that involve probabilistic models. What is it good for, and how does it work?

“The researchers only counted the number of different bacteria types in their samples, not the total cells. A CBS investigation earlier this year found bacteria including staphylococcus and E. coli on the Keurig machines it swabbed. More than half were harboring millions of bacteria cells.
Bacteria appear to thrive in the high temperatures and chemical makeup of the coffee making process itself. Neither user behavior, the type of coffee brewed, nor frequency of the machine’s use seemed to affect the composition of the bacteria present.”
