Information Theory, Inference and Learning Algorithms

Autor David J. C. MacKay
en Limba Engleză Hardback – 25 sep 2003

În peisajul academic actual, Information Theory, Inference and Learning Algorithms ocupă un loc central în programele de studiu ale facultăților de matematică, fizică și informatică, fiind o resursă fundamentală pentru înțelegerea tehnologiilor moderne. Remarcăm abordarea pedagogică inovatoare a lui David J. C. MacKay, care refuză să trateze teoria informației ca pe o disciplină izolată, integrând-o organic cu inferența și algoritmii de învățare. Această lucrare extinde cadrul propus de Elements of Information Theory de Thomas M. Cover prin adăugarea unei dimensiuni aplicative vaste, făcând trecerea de la limitele teoretice ale lui Shannon la implementări practice în bioinformatică și inginerie financiară.

Structura volumului este riguros organizată în secțiuni care facilitează o progresie logică: primele capitole stabilesc fundamentele probabilității și entropiei, urmate de blocuri tematice dedicate compresiei datelor și codării pentru canale cu zgomot. Subliniem faptul că autorul acordă o atenție deosebită codurilor de corecție a erorilor de ultimă generație, precum codurile „digital fountain”, esențiale pentru transmisia modernă de date. Spre deosebire de Information and Communication Theory de S Höst, care se concentrează pe sistemele de comunicare digitală, volumul de față explorează în profunzime metodele de inferență, inclusiv algoritmii Monte Carlo și rețelele neuronale. Cu un aparat ilustrativ bogat și 390 de exerciții, ediția publicată de Cambridge University Press funcționează atât ca manual universitar, cât și ca ghid de referință pentru profesioniștii care caută să stăpânească fundamentele matematice ale științei datelor.

De ce să citești această carte

Recomandăm această lucrare oricărui student sau profesionist care dorește să înțeleagă legătura profundă dintre teoria informației și inteligența artificială. Cititorul câștigă o bază matematică solidă și competențe practice prin rezolvarea celor peste 400 de exerciții propuse. Este un instrument esențial pentru a stăpâni algoritmii de inferență și codurile de corecție a erorilor utilizate în comunicațiile prin satelit și stocarea modernă a datelor.


Descriere scurtă

Information theory and inference, taught together in this exciting textbook, lie at the heart of many important areas of modern technology - communication, signal processing, data mining, machine learning, pattern recognition, computational neuroscience, bioinformatics and cryptography. The book introduces theory in tandem with applications. Information theory is taught alongside practical communication systems such as arithmetic coding for data compression and sparse-graph codes for error-correction. Inference techniques, including message-passing algorithms, Monte Carlo methods and variational approximations, are developed alongside applications to clustering, convolutional codes, independent component analysis, and neural networks. Uniquely, the book covers state-of-the-art error-correcting codes, including low-density-parity-check codes, turbo codes, and digital fountain codes - the twenty-first-century standards for satellite communications, disk drives, and data broadcast. Richly illustrated, filled with worked examples and over 400 exercises, some with detailed solutions, the book is ideal for self-learning, and for undergraduate or graduate courses. It also provides an unparalleled entry point for professionals in areas as diverse as computational biology, financial engineering and machine learning.

Recenzii

'This is an extraordinary and important book, generous with insight and rich with detail in statistics, information theory, and probabilistic modeling across a wide swathe of standard, creatively original, and delightfully quirky topics. David MacKay is an uncompromisingly lucid thinker, from whom students, faculty and practitioners all can learn.' Peter Dayan and Zoubin Ghahramani, Gatsby Computational Neuroscience Unit, University College, London
'This is primarily an excellent textbook in the areas of information theory, Bayesian inference and learning algorithms. Undergraduates and postgraduates students will find it extremely useful for gaining insight into these topics; however, the book also serves as a valuable reference for researchers in these areas. Both sets of readers should find the book enjoyable and highly useful.' David Saad, Aston University
'An utterly original book that shows the connections between such disparate fields as information theory and coding, inference, and statistical physics.' Dave Forney, Massachusetts Institute of Technology
'An instant classic, covering everything from Shannon's fundamental theorems to the postmodern theory of LDPC codes. You'll want two copies of this astonishing book, one for the office and one for the fireside at home.' Bob McEliece, California Institute of Technology
'… a quite remarkable work … the treatment is specially valuable because the author has made it completely up-to-date … this magnificent piece of work is valuable in introducing a new integrated viewpoint, and it is clearly an admirable basis for taught courses, as well as for self-study and reference. I am very glad to have it on my shelves.' Robotica
'With its breadth, accessibility and handsome design, this book should prove to be quite popular. Highly recommended as a primer for students with no background in coding theory, the set of chapters on error correcting codes are an excellent brief introduction to the elements of modern sparse graph codes: LDPC, turbo, repeat-accumulate and fountain codes are described clearly and succinctly.' IEEE Transactions on Information Theory
