摘要:

在本文中,我们提出了条件对抗网络(CAN),这是一个探索共享特征和标签预测之间关系的框架,用于多域文本分类(MDTC)。该方法引入了一个条件域变量来同时对共享特征表示和类感知信息中的域变量进行建模,并采用熵调节来保证共享特征的可传递性。我们提供的CAN框架的理论分析,表明CAN的目标是相当于最大限度地减少共享功能和标签预测的多个联合分布之间的总分歧。因此,CAN是一个理论上合理的对抗网络,可以区分多种分布。两个MDTC基准测试结果表明,CAN优于以前的方法。进一步的实验表明,CAN具有很好的能力,推广学习到未知领域的知识。

英文摘要:

In this paper, we propose conditional adversarial networks (CANs), a framework that explores the relationship between the shared features and the label predictions to impose more discriminability to the shared features, for multi-domain text classification (MDTC). The proposed CAN introduces a conditional domain discriminator to model the domain variance in both shared feature representations and class-aware information simultaneously and adopts entropy conditioning to guarantee the transferability of the shared features. We provide theoretical analysis for the CAN framework, showing that CAN's objective is equivalent to minimizing the total divergence among multiple joint distributions of shared features and label predictions. Therefore, CAN is a theoretically sound adversarial network that discriminates over multiple distributions. Evaluation results on two MDTC benchmarks show that CAN outperforms prior methods. Further experiments demonstrate that CAN has a good ability to generalize learned knowledge to unseen domains.
