Then the three weighings give the ternary expansion of the index of the odd coin. If the expansion is the same as the expansion in the matrix, it indicates that the coin is heavier. If the expansion is of the opposite sign, the coin is lighter.

Why does this scheme work? It is a single error correcting Hamming code for the ternary alphabet discussed in Section 8.

Here are some details. First note a few properties of the matrix above that was used for the scheme.

All the columns are distinct and no two columns add to 0,0,0. Also if any coin 14 Entropy, Relative Entropy and Mutual Information is heavier, it will produce the sequence of weighings that matches its column in the matrix. If it is lighter, it produces the negative of its column as a sequence of weighings.

Combining all these facts, we can see that any single odd coin will produce a unique sequence of weighings, and that the coin can be determined from the sequence. One of the questions that many of you had whether the bound derived in part a was actually achievable. For example, can one distinguish 13 coins in 3 weighings?

No, not with a scheme like the one above. Yes, under the assumptions under which the bound was derived.

The bound did not prohibit the division of coins into halves, neither did it disallow the existence of another coin known to be normal. Under both these conditions, it is possible to nd the odd coin of 13 coins in 3 weighings. You could try modifying the above scheme to these cases.

Drawing with and without replacement. An urn contains r red, w white, and b black balls. Which has higher entropy, drawing k 2 balls from the urn with replacement or without replacement?

Set it up and show why. There is both a hard way and a relatively simple way to do this.

Like these other volumes, Stimulated Recall and Mental Models is a vehicle for illustrating a particular methodology in order to demonstrate its potential and to show how to design, conduct, and report research according to its theoretical stance and characteristic procedures.

Consequently, information theory has emerged as a core foundation for the communications industry i. Thus, the basic foundations and assumptions of information theory continue to be studied by educators and students alike in many mathematically-grounded disciplines.

The authors examine information theory on two levels: The book contains 17 chapters that cover fundamental concepts associated with information theory; each chapter is accompanied by problems that instructors can assign to students.

These last chapters also emphasize material that has been added to the second edition, including universal source coding Chapter 13 , network information theory Chapter 15 , and portfolio theory Chap- ter While focusing on theory in later chapters seems counter-intuitive to the learning and teaching process, the approach is a sensible one in this context, since the later chapters provide students with intellectual space in which to place coding theorems learned in earlier chapters.

Additionally, the authors have reorganized the chapters in order to create a more teachable textbook, and have provided an updated reference list. Therefore, it is not an ideal choice by instructors for students who are interested in or curious about information theory but who do not have the academic or professional background necessary to sustain a successful learning experience.
