內(nèi)容簡(jiǎn)介

　　本書是一本機(jī)器學(xué)習(xí)實(shí)用指南，提供從基礎(chǔ)知識(shí)到進(jìn)階技能的全面學(xué)習(xí)路徑。本書以淺顯易懂的方式介紹了機(jī)器學(xué)習(xí)的基本概念和主要類型，并詳細(xì)介紹使用 Python 及常見(jiàn)的庫(kù)進(jìn)行數(shù) 據(jù)處理和機(jī)器學(xué)習(xí)的實(shí)操。此外，介紹了數(shù)據(jù)預(yù)處理的詳細(xì)過(guò)程，最后通過(guò)若干典型案例加深讀者對(duì)機(jī)器學(xué)習(xí)的理解。本書適合對(duì)機(jī)器學(xué)習(xí)感興趣的初學(xué)者，也可作為軟件開發(fā)人員、數(shù)據(jù)分析師、學(xué)術(shù)研究人員的參考書籍。
