With this practical book, you'll learn techniques for extracting and transforming features--the numeric representations of raw data--into formats for machine-learning models. Each chapter guides you through a single data problem, such as how to represent text or image data. Together, these examples illustrate the main principles of feature engineering. \u003c\/p\u003e\u003cp\u003e Rather than simply teach these principles, authors Alice Zheng and Amanda Casari focus on practical application with exercises throughout the book. The closing chapter brings everything together by tackling a real-world, structured dataset with several feature-engineering techniques. Python packages including numpy, Pandas, Scikit-learn, and Matplotlib are used in code examples. \u003c\/p\u003e\u003cp\u003e You'll examine: \u003c\/p\u003e\u003cul\u003e \u003cli\u003eFeature engineering for numeric data: filtering, binning, scaling, log transforms, and power transforms \u003c\/li\u003e\n\u003cli\u003eNatural text techniques: bag-of-words, n-grams, and phrase detection \u003c\/li\u003e\n\u003cli\u003eFrequency-based filtering and feature scaling for eliminating uninformative features \u003c\/li\u003e\n\u003cli\u003eEncoding techniques of categorical variables, including feature hashing and bin-counting \u003c\/li\u003e\n\u003cli\u003eModel-based feature engineering with principal component analysis \u003c\/li\u003e\n\u003cli\u003eThe concept of model stacking, using k-means as a featurization technique \u003c\/li\u003e\n\u003cli\u003eImage feature extraction with manual and deep-learning techniques \u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Alice Zheng, Amanda Casari\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1491953241\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781491953242\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e O'Reilly Media\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 05\/08\/2018\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 215\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.70lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.10h x 7.00w x 0.40d","brand":"Alice Zheng","offers":[{"title":"Paperback","offer_id":43995718648063,"sku":"9781491953242","price":65.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_a724c4f0-36db-4301-b24b-fefd9a8c39b3.jpg?v=1683337434","url":"https:\/\/www.whiterainbookhouse.com\/products\/feature-engineering-for-machine-learning-alice-zheng-9781491953242","provider":"WR Book House","version":"1.0","type":"link"}
