Improved Embedded Learning for Classification of Chinese Paintings

摘要: 现有中国画分类大多只考虑了画作和类标签的相关性,忽略了画作间的关联以及特征重要度的影响.为此,提出改进的嵌入式中国画分类算法.通过微调预训练的VGG-F模型提取中国画图像特征;并提出基于互信息的嵌入式学习算法,使"友情则近,敌对则远"的嵌入式原则受到特征选择及特征重要度的影响;最后利用支持向量机对中国画进行画作艺术风格及其作者分类.实现了对样本库中10位画家中国画的识别,平均准确率为86%,相比其他算法,该算法有更高的分类准确度和更好的鲁棒性.Abstract: The existing research on classification of Chinese paintings was limited to consideration of the relationship between paintings and labels,where the distribution information of paintings and feature importance were often ignored.Firstly,we extracted the features of Chinese paintings by fine-tuning VGG-F models.Then,the mutual information theory was introduced into the embedded machine learning,and formulated a new embedded classification algorithm to characterize the variation in artistic styling of the Chinese paintings.Finally,support vector machine was applied as the classifier to obtain satisfactory classification results.The average classification accuracy of 10 artists Chinese paintings is 86%.Experimental results support that the proposed algorithm outperforms the existing representative benchmarks.
