Aug 4, 2005 Computer Science > Information Theory This fact that cutoff rate can be `` created'' by channel splitting was noticed by Massey in his study of The eloquence with which Massey advocated the use of the cut-off rate (3) R. G. Gallager, Information Theory and Reliable Communication, Jolin Wiley, New. They were motivated by the fact that R, is the upper limit of code rates for which the average decoding computation per information bit is finite when sequential.
It is common in information theory to speak of the "rate" or "entropy" of a language. This is appropriate, for example, when the source of information is English prose. The rate of a source of information is related to its redundancy and how well it can be compressed, the subject of source coding . Information Rate. Lesson 3 of 15 • 7 upvotes • 12:40 mins. Save.

As the area under an ROC curve is a measure of the usefulness of a test in general, where a greater area means a more useful test, the areas under ROC curves are used to compare the usefulness of tests.

Ozarow, Member, IEEE, based on the cut-off rate R, [24] L. Martignon, in International Encyclopedia of the Social & Behavioral Sciences, 2001. Information theory is the mathematical treatment of the concepts, parameters and rules governing the transmission of messages through communication systems. It was founded by Claude Shannon toward the middle of the twentieth century and has since then evolved into a vigorous branch of mathematics fostering
