會(huì)員

本書全面地講解了在科學(xué)領(lǐng)域廣泛運(yùn)用的微積分、概率論與數(shù)理統(tǒng)計(jì)、線性代數(shù)、數(shù)值計(jì)算、多元統(tǒng)計(jì)分析等數(shù)學(xué)基礎(chǔ)知識(shí)。全書共6章:第1章介紹了大數(shù)據(jù)與數(shù)學(xué)、數(shù)學(xué)與Python的關(guān)系;第2章介紹了微積分的基礎(chǔ)知識(shí),包括極限、導(dǎo)數(shù)、微分、不定積分與定積分等;第3章介紹了概率論與數(shù)理統(tǒng)計(jì)的基礎(chǔ)知識(shí),包括數(shù)據(jù)分布特征、概率與概率分布、參數(shù)估計(jì)、假設(shè)檢驗(yàn)等;第4章介紹了線性代數(shù)的基礎(chǔ)知識(shí),包括行列式、矩陣的運(yùn)算和特征分解、奇異值分解;第5章介紹了數(shù)值計(jì)算的基礎(chǔ)知識(shí),包括插值法、函數(shù)逼近與擬合、非線性方程(組)求根;第6章介紹了常用的多元統(tǒng)計(jì)分析方法,包括回歸分析、判別分析、聚類分析、主成分分析、因子分析和典型相關(guān)分析。本書示例大都結(jié)合Python進(jìn)行求解分析,且每章都有課后習(xí)題,可以幫助讀者鞏固所學(xué)的內(nèi)容。

Spark 3.0大數(shù)據(jù)分析與挖掘:基于機(jī)器學(xué)習(xí)
會(huì)員

Spark作為新興的、應(yīng)用范圍廣泛的大數(shù)據(jù)處理開源框架,吸引了大量的大數(shù)據(jù)分析與挖掘從業(yè)人員進(jìn)行相關(guān)內(nèi)容的學(xué)習(xí)與開發(fā),其中ML是Spark3.0機(jī)器學(xué)習(xí)框架使用的核心。本書用于Spark3.0ML大數(shù)據(jù)分析與挖掘入門,配套示例源碼、PPT課件、數(shù)據(jù)集、思維導(dǎo)圖、開發(fā)環(huán)境和作者答疑服務(wù)。本書共分13章,從Spark3.0大數(shù)據(jù)分析概述、基礎(chǔ)安裝和配置開始,依次介紹ML的DataFrame、ML的基本概念,以及協(xié)同過濾、線性回歸、分類、決策樹與隨機(jī)森林、聚類、關(guān)聯(lián)規(guī)則、數(shù)據(jù)降維、特征提取和轉(zhuǎn)換等數(shù)據(jù)處理方法;最后通過經(jīng)典的鳶尾花分析實(shí)例,回顧前面的學(xué)習(xí)內(nèi)容,實(shí)現(xiàn)了一個(gè)完整的數(shù)據(jù)分析與挖掘過程。本書采取實(shí)例和理論相結(jié)合的方式,講解細(xì)致直觀,示例豐富,適合Spark3.0機(jī)器學(xué)習(xí)初學(xué)者、大數(shù)據(jù)分析和挖掘人員,也適合高等院校和培訓(xùn)機(jī)構(gòu)人工智能與大數(shù)據(jù)相關(guān)專業(yè)的師生教學(xué)參考。
