面向?qū)Ρ葘W(xué)習(xí)的高效協(xié)同處理與優(yōu)化方法研究摘要：

隨著大數(shù)據(jù)時(shí)代的到來，對(duì)于數(shù)據(jù)挖掘和機(jī)器學(xué)習(xí)的應(yīng)用需求越來越高。而面向?qū)Ρ葘W(xué)習(xí)的算法不僅能夠滿足數(shù)據(jù)挖掘和機(jī)器學(xué)習(xí)的需求，還能夠在各種應(yīng)用中展現(xiàn)出優(yōu)異的性能。然而，對(duì)于面向?qū)Ρ葘W(xué)習(xí)的算法，其模型的訓(xùn)練過程中難免會(huì)遇到高計(jì)算量、模型過擬合等問題，這就要求我們?cè)趨f(xié)同處理和優(yōu)化方法上下功夫。

本論文針對(duì)面向?qū)Ρ葘W(xué)習(xí)的高效協(xié)同處理與優(yōu)化方法進(jìn)行了研究。首先，本文通過對(duì)比多個(gè)經(jīng)典的面向?qū)Ρ葘W(xué)習(xí)算法，找到了其中的優(yōu)缺點(diǎn)，并提出了一種基于卷積神經(jīng)網(wǎng)絡(luò)的新型算法。其次，本文從協(xié)同處理的角度出發(fā)，研究了如何通過分布式計(jì)算、并行計(jì)算和多核計(jì)算等方式提高算法的效率。最后，本文根據(jù)模型訓(xùn)練過程中的過擬合問題，提出了一種基于正則化的優(yōu)化方法，通過懲罰模型的復(fù)雜度，提高模型的泛化能力。

本文的研究成果表明，本文所提出的面向?qū)Ρ葘W(xué)習(xí)算法基于卷積神經(jīng)網(wǎng)絡(luò)的算法不僅效果更好，而且計(jì)算速度更快。同時(shí)，通過采用分布式計(jì)算、并行計(jì)算和多核計(jì)算等方式，可以極大地提高算法的運(yùn)行效率。最后，本文提出的基于正則化的優(yōu)化方法，能夠有效地避免模型過擬合問題，保證模型的泛化能力。
