Python machine learning

PyTorch是Facebook於2017年初在機器學習和科學計算工具Torch的基礎上，針對Python語言發佈的一個全新的機器學習工具套件，一經推出便受到業界廣泛關注和討論，目前已經成為機器學習從業人員首選的一款研發工具。 本書是使用PyTorch建構神經網絡模型的實用指南，內容分為9章，包括PyTorch與深度學習的基礎知識、神經網路的構成、神經網路的高階知識、機器學習基礎知識、深度學習在電腦視覺上的應用、深度學習在序列資料和文字當中的應用、生成網路、現代網路架構，以及PyTorch與深度學習的未來走向。 本書適合對深度學習領域感興趣且希望一探PyTorch究竟的業界人士閱讀。具備其他深度學習框架使用經驗的讀者，也可以透過本書掌握PyTorch的用法。 本書範例檔： https://github.com/PacktPublishing/Deep-Learning-with-PyTorch

資料科學、機器學習是近來最夯的關鍵字，引發的學習熱潮從未間斷，如果您正尋找資料科學、AI 的入門書，本書就是您的 Mr. Right！【獨家資料科學 5 步驟，記牢、做熟這 5 步就夠了！】只要上網 google "資料料學" 一定會發現，出現的關鍵字實在超級廣，包括 AI、機器學習、程式設計、資料視覺化、數學、統計...等等，這麼雜到底怎麼開始？總不可能通通碰過一輪？！初學者看這本最適合！本書大聲告訴您：「資料科學沒那麼複雜！」，只要跟著書中精心設計的「資料科學 5 步驟」，記牢、做熟這 5 步就夠了！問個感興趣的問題 → 資料取得 → 資料處理 → 探索性資料分析 → 機器學習做資料分析【用 Excel 輕鬆實作機器學習，跟複雜的程式說掰掰！】機器學習 (Machine Learning) 是資料科學實作非常重要的一環，很多書都告訴您必須碰程式，這也讓非 IT 背景的初學者相當苦手，本書正是程式苦手者的超級救星！Excel 是多數人都很熟悉的工具，這本書能讓各種不同學習背景和工作性質的讀者受惠，再也不限 IT 背景才能學。再者，用程式來實作機器學習雖然「省事」，卻也「省略很多事」，若沒有自己細心研究，可能連資料集長什麼樣子都模模糊糊；而在訓練機器學習模型時也是一樣，程式往往把模型封裝成內部在做什麼都神神祕祕的黑盒子，三兩下就告訴您「模型訓練好了！」，到頭來只能虛虛地感覺自己「好像」學會了。反觀 Excel 除了易學，還多了能細細觀察模型內部運作細節的優點！首先，數據資料都清清楚楚攤在儲存格上，再也不是看不到摸不到！而本書所介紹的【線性迴歸】、【KNN】、【K-Means】、【深度學習】等機器學習演算法，只需用到簡單幾個的 Excel 函數就可以輕鬆操作，讀者可以觀察公式清楚看出模型各階段的數據是怎麼算出來的；最後，書中各模型的工作表佈局和配色也都經過精心安排，希望透過種種設計讓讀者更容易掌握模型細部的運作細節！本書特色: □ 用最熟悉的 Excel 馬上可以動手做！□ 精心設計豐富插圖，每一頁都有感！ □ 零數學公式、統計符號，輕鬆學會資料科學、機器學習！□ 機器學習實戰演練：線性迴歸分析、KNN 分類、K-Means 分群、深度學習分類□ 範例滿載！一次不熟換個範例多 run 幾次保證讓您會！

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
