摘要

摘要

En 中文
随着深度学习的发展,卷积神经网络(CNNs)已成为图像分类的主流方法,而ResNet架构的出现显著加速了这一进程。然而,随着模型深度的增加,特征冗余限制了模型性能。尽管像主成分分析(PCA)这样的传统机器学习方法可以有效去除冗余特征,但目前尚无有效方法将PCA作为特征提取技术整合到不同的卷积神经网络架构中。本研究提出了一种选择性主成分层(SPCL),这是一种将PCA有效整合到卷积神经网络中以筛选关键特征并提升深度学习模型特征表示能力的方法。SPCL应用于ResNet架构模型,以减少冗余特征并增强图像分类任务中的泛化性能。在CIFAR-10和Tiny ImageNet数据集上的评估证明了其有效性。结果表明,SPCL可普遍应用于ResNet架构模型,提升模型精度,在无需显著增加计算开销的情况下平衡模型性能与稳定性的提升,展现出其在复杂图像分类任务中增强性能的潜力。
