Python machine learning

現在學機器學習，正是最好的年代！在過去要處理資料，就要用C語言撰寫函數；在Python裡，別人已寫好了許多套件，只要像是在玩樂高積木一樣，就能完成你想要的結果。因此我會說，現在是學機器學習最好的時候，你等於是站在巨人的肩膀上學習。本書沒有複雜的數學，沒有複雜的程式碼，以有系統的編排，引領你進入機器學習的世界。我們會介紹sklearn的資料預處理；簡單線性迴歸、多元線性迴歸、羅吉斯迴歸、K最近鄰、支持向量機、決策樹、隨機森林等監督式的機器學習模型。而在非監督模型上會介紹Kmeans。另外，大部分的書不會強調的ColumnTransformer、管道器製作。許多書沒有解釋清楚的模型預測重要指標：正確率、精確率、召回率、混亂矩陣、綜合報告、PRC曲線、ROC曲線，我們也會一次詳細說明，讓你一手掌握。實例演練時會操作中英文的文字處理，並做情感分析和主題探索。還有知名的大數據資料庫，包括波斯頓房價預測、鳶尾花資料、鐵達尼號資料、威斯康辛大學醫院收集的乳癌腫瘤病患預測、電信公司客戶流失預測、信用卡盜刷預測、Newsgroup新聞群組分類、Amazon商品評論預測、Tripadvisor裡兩家航空公司和數字預測。最後教大家如何將深度學習的模組也包裝到sklearn。現在就讓我們一起學習Python，用機器學習掌握人工智慧。

【新書簡介】★☆★ 全面掌握機器學習的影像處理，豐富實例等你來挖掘！ ★☆★機器學習的影像處理，是當前最熱門的研究領域之一，而這其中OpenCV-Python整合了OpenCV C++API和Python的最佳特性，使其成為電腦視覺領域內極具影響力和實用性的工具。本書透過案例來介紹所有影像相關的技術，包含了基礎演算法、機器學習、深度學習。在基礎部分，有影像安全（影像加密、影像關鍵部位打碼、隱身術）、影像辨識（答題卡辨識、手勢辨識、車牌辨識、指紋辨識、手寫數字辨識）、物體計數、影像檢索、缺陷檢測等。在機器學習部分，則實作了KNN實現字元（手寫數字、英文字母）辨識、數獨影像求解（KNN）、SVM手寫數字辨識、行人檢測、藝術畫（K平均值聚類）等。在深度學習方面，包括了影像分類、物件辨識（YOLO演算法、SSD演算法）、語義分割、實例分割、風格遷移、姿勢辨識等。另外在最流行的人臉辨識相關方面，則提供了人臉檢測、人臉辨識、勾勒五官輪廓、人臉對齊、表情辨識、駕駛員疲勞檢測、易容術、性別和年齡辨識等。本書對電腦視覺涉及的基礎知識進行了全面且系統性的深入梳理，能夠幫助讀者快速掌握該領域的核心基礎知識，此外，透過豐富的實例介紹，也能避免將案例作為單一問題看待的窘境，並且可以從不同的角度理解及分析問題，讓讀者能夠加以組合運用，創建屬於自己獨特的影像處理法寶！※ 本書附程式碼，可至深智官網下載：https://deepmind.com.tw/

“Vanderbilt elegantly and persuasively tackles one of the most pernicious of the lies we tells ourselves—that the pleasures of learning are reserved for the young.” —Malcolm Gladwell, bestselling author of Outliers“Vanderbilt elegantly and persuasively tackles one of the most pernicious of the lies we tells ourselves—that the pleasures of learning are reserved for the young.” —Malcolm Gladwell, bestselling author of OutliersWhy do so many of us stop learning new skills as adults? Are we afraid to be bad at something? Have we forgotten the sheer pleasure of beginning from the ground up? Inspired by his young daughter’s insatiable curiosity, Tom Vanderbilt embarks on a yearlong quest of learning—purely for the sake of learning. Rapturously singing Spice Girls songs in an amateur choir, losing games of chess to eight-year-olds, and dodging scorpions at a surf camp in Costa Rica, Vanderbilt tackles five main skills but learns so much more. Along the way, he interviews dozens of experts abo
