摘要

摘要: 在机器学习中,迁移学习被证明能有效使用一个领域信息提高另一个领域中受训模型的分类精度. 迁移学习总是假设相关领域间共享某些隐含因素,但在当前的迁移学习方法中,该部分隐含因素依然未得到充分探讨.本研究引入低维共享隐空间的迁移学习方法,基于经典支持向量机(Support vector machine, SVM)分类模型得到融入共享隐空间的迁移支持向量机,该模型较以往相关方法能更好地利用隐空间这一有效信息,从而提高所得分类器的泛化性能.相关实验结果亦验证了所提方法的有效性.

Abstract: In machine learning, transfer learning is proved to be able to efficiently use the information of one domain to enhance the classification accuracy in another domain. Transfer learning always assumes that the related domains share some correlated latent factors. But the existing transfer learning methods cannot make full use of these latent factors. So a low dimensionality shared latent subspace transfer learning method is proposed. Specifically, a shared latent subspace transfer support vector machine model is proposed in contrast to the classical support vector machine (SVM) model. Compared with traditional transfer learning methods, the proposed method can make better use of the latent subspace, therefore it can enhance the transfer classification performance. Experimental results confirm the efficiency of the proposed method.
