新時(shí)代·技術(shù)新未來(lái)自動(dòng)機(jī)器學(xué)習(xí)(AutoML):方法、系統(tǒng)與挑戰(zhàn) 內(nèi)容簡(jiǎn)介

本書全面介紹自動(dòng)機(jī)器學(xué)習(xí),主要包含自動(dòng)機(jī)器學(xué)習(xí)的方法、實(shí)際可用的自動(dòng)機(jī)器學(xué)習(xí)系統(tǒng)及目前所面臨的挑戰(zhàn)。在自動(dòng)機(jī)器學(xué)習(xí)方法中,本書涵蓋超參優(yōu)化、元學(xué)習(xí)、神經(jīng)網(wǎng)絡(luò)架構(gòu)搜索三個(gè)部分,每一部分都包括詳細(xì)的內(nèi)容介紹、原理解讀、具體運(yùn)用方法和存在的問(wèn)題等。此外,本書還具體介紹了現(xiàn)有的各種可用的AutoML系統(tǒng),如Auto-sklearn、Auto-WEKA及Auto-Net等,并且本書很后一章詳細(xì)介紹了具有代表性的AutoML挑戰(zhàn)賽及挑戰(zhàn)賽結(jié)果背后所蘊(yùn)含的理念,有助于從業(yè)者設(shè)計(jì)出自己的AutoML系統(tǒng)。 本書英文版是靠前上本介紹自動(dòng)機(jī)器學(xué)習(xí)的英文書,內(nèi)容全面且翔實(shí),尤為重要的是涵蓋了近期新的AutoML領(lǐng)域進(jìn)展和難點(diǎn)。本書作者和譯者學(xué)術(shù)背景扎實(shí),保證了本書的內(nèi)容質(zhì)量。 對(duì)于初步研究者,本書可以作為其研究自動(dòng)機(jī)器學(xué)習(xí)方法的背景知識(shí)和起點(diǎn);對(duì)于工業(yè)界從業(yè)人員,本書全面介紹了AutoML系統(tǒng)及其實(shí)際應(yīng)用要點(diǎn);對(duì)于已經(jīng)從事自動(dòng)機(jī)器學(xué)習(xí)的研究者,本書可以提供一個(gè)AutoML近期新研究成果和進(jìn)展的概覽?傮w來(lái)說(shuō),本書受眾較為廣泛,既可以作為入門書,也可以作為專業(yè)人士的參考書。
