摘要：

隨著物聯(lián)網(wǎng)技術(shù)的不斷普及和邊緣計算的不斷發(fā)展，邊緣端設(shè)備處理大量數(shù)據(jù)和高復(fù)雜度計算的需求與日俱增。傳統(tǒng)的訓(xùn)練模型過程需要大量的計算資源和帶寬，且模型訓(xùn)練時間較長，不能滿足快速響應(yīng)和實時性的要求。因此，基于邊緣計算的分布式機器學(xué)習(xí)算法成為了研究的焦點。

本文通過對邊緣計算和分布式機器學(xué)習(xí)算法的研究，探討了在邊緣計算場景下的分布式機器學(xué)習(xí)算法。首先，介紹了邊緣計算與分布式機器學(xué)習(xí)算法的基本概念和發(fā)展歷程。然后，分析了邊緣計算場景下分布式機器學(xué)習(xí)算法面臨的挑戰(zhàn)和難點，包括計算資源受限、網(wǎng)絡(luò)延遲、數(shù)據(jù)安全等問題，并結(jié)合當前研究進展進行了總結(jié)。接著，闡述了分布式機器學(xué)習(xí)算法在邊緣計算場景下的應(yīng)用領(lǐng)域和優(yōu)勢，包括智能交通、智能工廠、醫(yī)療保健等領(lǐng)域。最后，提出了未來的研究方向和重點，主要包括邊緣計算與分布式機器學(xué)習(xí)算法融合、多任務(wù)協(xié)同分布式學(xué)習(xí)、差分隱私保護分布式學(xué)習(xí)等方面的實現(xiàn)方法和優(yōu)化。
