Deep Learning Illustrated de Aglae Bassens

Deep Learning Illustrated: Addison-Wesley Data & Analytics Series

Autor Aglae Bassens, Grant Beyleveld, Jon Krohn
en Limba Engleză Paperback – 17 dec 2019

Prin parcurgerea acestui volum, cititorul va reuși să implementeze modele funcționale de rețele neuronale profunde folosind cele mai relevante biblioteci actuale: TensorFlow (cu API-ul Keras), PyTorch și Coach. Observăm că Deep Learning Illustrated reușește să demistifice un domeniu adesea arid, transformând abstractizările matematice în soluții software concrete pentru viziune artificială, procesarea limbajului natural sau generarea de conținut vizual prin algoritmi. Cititorul care a aplicat ideile din Deep Learning de Andrew Glassner va găsi aici o continuare naturală, care face trecerea de la înțelegerea vizuală la execuția efectivă în Python. Considerăm că punctul forte al lucrării este echilibrul dintre teorie și pragmatism: conceptele biologice ale vederii sau structura limbajului sunt imediat cuplate cu exemple de cod și caiete de lucru Jupyter, facilitând o progresie rapidă. Structura cărții este organizată intuitiv, pornind de la fundamentul istoric și terminologic în Partea I, explorând apoi în detaliu aplicații specifice. Capitolele dedicate 'Machine Art' și 'Game-Playing Machines' sunt deosebit de relevante pentru cei interesați de rețele generative și învățare prin recompensă (Reinforcement Learning). Spre deosebire de Python Deep Learning de Ivan Vasilev, care menține un ton tehnic tradițional, volumul de față prioritizează intuiția vizuală și accesibilitatea, fără a sacrifica rigoarea necesară pentru a construi sisteme AI capabile să rezolve probleme din lumea reală.

De ce să citești această carte

Recomandăm această carte profesioniștilor și studenților care doresc să treacă pragul de la curiozitate la execuție în domeniul inteligenței artificiale. Câștigul imediat este capacitatea de a construi și antrena modele de Deep Learning fără a fi blocați în formalism matematic excesiv. Este resursa ideală pentru cei care învață cel mai bine prin exemple vizuale și practică directă în cod Python.

Descriere scurtă

Deep learning is one of today's hottest fields. This approach to machine learning is achieving breakthrough results in some of today's highest profile applications, in organizations ranging from Google to Tesla, Facebook to Apple. Thousands of technical professionals and students want to start leveraging its power, but previous books on deep learning have often been non-intuitive, inaccessible, and dry. In Deep Learning Illustrated, three world-class instructors and practitioners present a uniquely visual, intuitive, and accessible high-level introduction to the techniques and applications of deep learning. Packed with vibrant, full-color illustrations, it abstracts away much of the complexity of building deep learning models, making the field more fun to learn, and accessible to a far wider audience.Part I's high-level overview explains what Deep Learning is, why it has become so ubiquitous, and how it relates to concepts and terminology such as Artificial Intelligence, Machine Learning, Artificial Neural Networks, and Reinforcement Learning. These opening chapters are replete with vivid illustrations, easy-to-grasp analogies, and character-focused narratives.Building on this foundation, the authors then offer a practical reference and tutorial for applying a wide spectrum of proven deep learning techniques. Essential theory is covered with as little mathematics as possible, and illuminated with hands-on Python code. Theory is supported with practical "run-throughs" available in accompanying Jupyter notebooks, delivering a pragmatic understanding of all major deep learning approaches and their applications: machine vision, natural language processing, image generation, and videogaming.To help readers accomplish more in less time, the authors feature several of today's most widely-used and innovative deep learning libraries, including TensorFlow and its high-level API, Keras; PyTorch, and the recently-released high-level Coach, a TensorFlow API that abstracts away the complexity typically associated with building Deep Reinforcement Learning algorithms.
