檢索匹配:深度學(xué)習(xí)在搜索、廣告、推薦系統(tǒng)中的應(yīng)用
會員

《檢索匹配:深度學(xué)習(xí)在搜索、廣告、推薦系統(tǒng)中的應(yīng)用》主要介紹了深度學(xué)習(xí)在互聯(lián)網(wǎng)核心的三大類業(yè)務(wù)(搜索、廣告、推薦系統(tǒng))檢索系統(tǒng)中的應(yīng)用。書中詳細講述了檢索匹配的理論、演進歷史,以及在業(yè)務(wù)中落地一個基于深度學(xué)習(xí)算法模型的全流程技能,包括業(yè)務(wù)問題建模、樣本準(zhǔn)備、特征抽取、模型訓(xùn)練和預(yù)測等,并提供了相應(yīng)的代碼。《檢索匹配:深度學(xué)習(xí)在搜索、廣告、推薦系統(tǒng)中的應(yīng)用》共11章,分為四大部分。第1部分(第1~2章)介紹了深度學(xué)習(xí)的相關(guān)理論知識;第2部分(第3~6章)介紹了業(yè)務(wù)中如何上線一個深度學(xué)習(xí)模型,包括標(biāo)簽拼接、特征抽取、模型訓(xùn)練和預(yù)測等流程,采用單機實現(xiàn);第3部分(第7~9章)介紹了檢索算法基本理論以及演進歷史,并以業(yè)內(nèi)應(yīng)用較為廣泛的雙塔模型DSSM為例進行了詳細理論解析和代碼實現(xiàn);第4部分(第10~11章)介紹了如何將單機訓(xùn)練模式改造為分布式訓(xùn)練模式,以加快模型的訓(xùn)練速度,從而應(yīng)對具有海量樣本的業(yè)務(wù)場景。
