Hidden Markov Models (HMMs). A hidden Markov model models a Markov process, but assumes that there is uncertainty in what state the system is in at any given time. A common metaphor is to think of the HMM as if the Markov Model were a mechanism hidden behind a curtain.
For the scientific journal, see Molecules (journal) . 3D (left and center) and 2D (right) representations of the terpenoid molecule atisane. A molecule (/ËmÉlÉªkjuËl/ from Latin moles mass) is an electrically neutral group of two or more atoms held together by chemical bonds.
A molecule, or the simplest structural unit of a substance that still keeps the properties of that substance, is a scientific word that gets used by the nonscientific, as in Every single molecule in my body wants that chocolate cake!. The only problem with molecules really, is that people confuse them with atoms.
