Uczenie maszynowe na Raspberry Pi

Donald Norris

Rozwijaj i replikuj interesujące eksperymenty uczenia maszynowego (ML) przy użyciu kamery Pi Camera i płytki Raspberry Pi. Niniejsza książka zapewnia solidny przegląd technik uczenia maszynowego i niezliczonych zagadnień leżących u jego podstaw, zachęcając do ich dalszego poznawania. Nietechniczne omówienia równoważą złożone objaśnienia techniczne, sprawiając, że najnowszy i najbardziej złożony temat w świecie hobbystów informatyki staje się zrozumiały i przystępny. Uczenie maszynowe, odwołujące się zwykle także do uczenia głębokiego (DL) jest obecnie zintegrowane z mnóstwem komercyjnych produktów, a także szeroko stosowane w przemyśle, medycynie i wojskowości. Trudno znaleźć jakąkolwiek nowoczesną działalność człowieka, która nie została "dotknięta" przez aplikacje sztucznej inteligencji (AI). Bazując na koncepcjach wprowadzonych w książce Beginning Artificial Intelligence with the Raspberry Pi, niniejsza książka prowadzi poza proste rozumienie koncepcji AI do rzeczywistych doświadczeń z wykorzystaniem uczenia maszynowego i praktycznych zastosowań koncepcji uczenia głębokiego w eksperymentach związanych z rozpoznawaniem obrazów przy użyciu płytki Pi. Koncepcje związane z uczeniem maszynowym na Raspberry Pi można przenieść na inne platformy, wchodząc jeszcze dalej w świat sztucznej inteligencji i uczenia maszynowego, aby realizować coraz lepsze projekty hobbystyczne lub komercyjne.

UML 2.0 in Action: A project-based tutorial. A detailed and practical book and eBook walk-through showing how to apply UML to real world development projects

Philippe Baumann, Patrick Grassle, Henriette Baumann, Galileo...

Most books about UML describe it almost in its entirety. Inevitably you're left with only a superficial knowledge of the range of UML elements, without a deep and intuitive understanding of how to apply UML as a whole to real world design problems. This book doesn't set out to cover all of UML, but instead pulls together those parts of UML with immediate practical relevance and presents them as part of a coherent process for using UML in your actual development projects.This book is designed to be read while you work on a real project. After an initial review of the essentials of UML and the design process, it begins with the modeling of a business system and its business processes, in this case an airport. Then the IT system intended to serve that business process is described and analysed. Finally the integration of the system into the production environment is covered in detail. The book can be used in two ways: it can be read through as a thorough grounding in how UML really works in practice; in addition it can be used as stand alone guide to that particular aspect of your own project. Both result in an intuitive understanding of how to actually use UML.
