| 摘 要： | 为了充分利用图像本身的结构信息并充分压缩图像数据，把得到的子空间中数据(反馈)的稀疏性作为约束项加入非负张量分解目标函数中，即采用基于反馈稀疏约束的非负张量分解算法对图像集合进行降维。最后，将该算法应用于手写数字图像库中，实验结果表明所提出的方法能有效改善图像分类的准确性

| Abstract: | In order to fully use the structural information of the data, and compress the image data, the sparse constraints of the subspace (feedback) were applied to the object function of non-negative tensor factorization. Then this algorithm was used to reduce the dimension of the image sets. Finally, image classification was realized. The experimental results on the handwritten digital image database show that the proposed algorithm can effectively improve the accuracy of the image classification. |
