手写数字识别是计算机视觉的基础挑战，广泛应用于邮政编码读取和文档数字化。本文提出一种基于集成的学习方法，将卷积神经网络（CNN）与传统机器学习技术结合，以提升识别准确率和鲁棒性。我们在包含70,000张手写数字图像的MNIST数据集上评估该方法。混合模型利用CNN进行特征提取，使用支持向量机（SVM）进行分类，达到99.30%的准确率。我们还研究了数据增强及多种集成技术对性能的提升效果。结果表明，该方法不仅实现高精度，还在不同书写风格下表现出更强的泛化能力。研究成果有助于构建更可靠的的手写数字识别系统，并凸显了深度学习与传统机器学习结合在模式识别中的潜力。
原文摘要 · Abstract (English)
Handwritten digit recognition remains a fundamental challenge in computer vision, with applications ranging from postal code reading to document digitization. This paper presents an ensemble-based approach that combines Convolutional Neural Networks (CNNs) with traditional machine learning techniques to improve recognition accuracy and robustness. We evaluate our method on the MNIST dataset, comprising 70,000 handwritten digit images. Our hybrid model, which uses CNNs for feature extraction and Support Vector Machines (SVMs) for classification, achieves an accuracy of 99.30%. We also explore the effectiveness of data augmentation and various ensemble techniques in enhancing model performance. Our results demonstrate that this approach not only achieves high accuracy but also shows improved generalization across diverse handwriting styles. The findings contribute to the development of more reliable handwritten digit recognition systems and highlight the potential of combining deep learning with traditional machine learning methods in pattern recognition tasks.
