An introduction to maximum entropy

Show Summary Details

Preview

Maximum entropy methods are used in crystallography for estimating reflection phases among other applications. This chapter explains the basic concepts behind maximum entropy, including entropy itself and its relationship to probability and information. They are illustrated by a simple non-scientific example of estimating missing information based on reasonable assumptions.

Keywords: maximum entropy; entropy; disorder; probability; information; direct methods; phases; electron density maps

Chapter.  2381 words.  Illustrated.
