Highlighting several versions of the flexible, powerful maximum entropy (ME) method, this reference provides strategies for solving various practical, inverse, and underdetermined problems. "Maximum Entropy to Scientific Problems" explores the advantages and disadvantages of using different methods to solve complex underdetermined problems and backs up all solutions with specific examples as actual proof of the success of any given method. Many important topics are covered such as statistical uncertainty, assurance, the "Prony method" of pole-zero modelling, sampling theory and others.
