An Introduction to Information Theory, Symbols, Signals and Noise

I wish every topic had a book like this one to introduce newcomers. Information theory is itself fairly interesting, but I found that the author used intriguing examples from a broad variety of disciplines to capture the reader's attention. He also has something of a self-deprecating writing style that will bring a smile to your face once or twice in each chapter. I loved the discussion of language and letter frequency, and it was even more interesting since now easily accessible tools exist (like Google's ngram) which allow you to explore some of the data and concepts first hand. I've explored various error correction/detection schemes online to gain a cursory understanding - this book did far more for me thanks to the simple and straightforward examples. I feel confident I could write my own (albeit basic) error correction code now, thanks solely to this book. I admit that the n-dimensional hypersphere-based code correction is somewhat beyond an easy implementation for me, but still, the explanation is engaging and I feel confident that I can explain the basics of geometrical error correction codes on a high level, which will be useful to me in my course of work. Anyhow, this kind of book, with enough depth to be challenging for someone with a basic science background yet still casual enough to read a bit here and there without getting lost, is a rare find. Well worth the very reasonable price. I wager that even someone with little interest in science or math could find some very interesting gems here. Have a deamy day.

This book was at the time very good for introduction in the field of information theory. From this point of view it is still very valuable. However, the filed has much evolved and possibly one might want to start reading some more modern introductory textbook.

Very interesting deep dive into information theory for beginners. The author includes tons of examples, equations, and illustrations that help drive home core concepts of information theory. A must read for anyone interested in the field.

Excelente experiência.
