maximum entropy method

"Maximum entropy method (MEM)" is a method, which originates from the information theory, to deduce the most provable solution through maximizing the information entropy when information (measurement) is insufficient. It is well known that it has been successfully applied to the crystal structure analysis by X-ray powder diffraction. For TEM, it is used in the case of EELS spectra, to obtain the inherent spectra by removing the effect of the energy spread of the incident electron beam.
