Augment your knowledge of Python with this entertaining learning guide, which features 100 exercises and programming puzzles and solutions. Python Challenges will help prepare you for your next exam or a job interview, and covers numerous practical topics such as strings, data structures, recursion, arrays, and more.Each topic is addressed in its own separate chapter, starting with an introduction to the basics and followed by 10 to 15 exercises of various degrees of difficulty, helping you to improve your programming skills effectively. Detailed sample solutions, including the algorithms used for all tasks, are included to maximize your understanding of each area. Author Michael Inden also describes alternative solutions and analyzes possible pitfalls and typical errors.Three appendices round out the book: the first covers the Python command line interpreter, which is often helpful for trying out the code snippets and examples in the book, followed by an overview of Pytest for unit te

內容介紹: 別再傻傻只選一個模型訓練很多模型，卻不知道應該選哪一個？沒有一個模型達標？每個模型都有其優缺點，無法取捨？小朋友才做選擇，大人全都要！你該試試集成式學習！集成式學習是使用 2 種或更多的機器學習演算法，來組合出預測能力更好的模型。DeepMind 已經使用集成式學習來組合多個神經網路，控制 Google 資料中心的運作效能；集成式學習技術也在 Kaggle 平台上，席捲了各個競賽的第一名寶座。因此，集成式學習是建立出更具威力的模型，不可或缺的技術之一。本書會介紹實務上常見的集成式學習演算法，如硬投票、軟投票、堆疊法、自助聚合法、適應提升法、梯度提升法、隨機森林、極端隨機樹等，並且使用熱門的 scikit-learn、Keras、OpenEnsembles、XGBoost 等 Python 函式庫來實作各種不同的集成式學習技術，建構出一個強大的模型。熟稔本書的內容後，不但可以精通集成式學習，在實際情境中面對問題時，亦能具備充分的專業知識判斷適用的集成式學習方法，並成功實作它們。書中採用「做中學」的方式，讓你不僅可以快速掌握理論基礎，也能了解各種集成式學習技術的實作，再加上運用真實世界中的資料集，你將能夠建立出更佳的機器學習模型，以解決各種問題，包含迴歸、分類、分群。現在翻開本書，讓我們一起進入集成式學習的世界，整合你所會的全部技術，打造最強大的模型。 本書特色: ● 繁體中文第 1 本集成式學習專書，告訴你不要再傻傻地只選一個模型● 完整介紹集成式學習中常見的演算法，包含極端隨機樹、堆疊法、自助聚合法、提升法等● 一書掌握實作集成式學習的必備套件，如 Scikit-Learn、OpenEnsembles、XGBoost 等● 用 Python 刻演算法給你看，接著告訴你怎麼用套件。讓你不只會做，還懂為什麼這麼做● 以 5 個實務案例來展示集成式學習的威力● 本書由施威銘研究室監修，內容易讀易懂，並加入大量「小編補充」補充必要知識● 本書 Python 範例程式免費下載

What's the point of art?This is the question Henri asks himself when his class is taken on a school trip to the local art gallery. Who wants pictures of old soup cans or melting watches? But when he encounters a painting with the most perfect blue, it creates a beautiful feeling. It's blueberries, oceans, summer skies and butterflies all rolled into one.And then he wanders into a room with a chair and a sign that reads "Is this really a chair?" Henri decides to test it out, unleashing an explosion of creativity! Finally Henri understands what art is all about... Following Isabelle Marinov's successful Leo and the Octopus, this is a fun and encouraging story of a boy learning to appreciate art and its boundless creativity.
