摘要:

这项工作研究了深度生成模型,它允许我们使用来自一个领域的训练数据为另一个领域构建模型。我们提出了变分双域三重自动编码器(VBTA),学习一个联合分布的对象从不同的领域。我们通过从跨域共享潜在空间采样的相对约束或三元组来扩展VBTA目标函数。换句话说,我们将深度生成模型与度量学习思想相结合,以便使用三元组信息改进最终目标。VBTA模型的性能表现在不同的任务:图像到图像的翻译,双向图像生成和跨语言文档分类。

英文摘要:

The work investigates deep generative models, which allow us to use training data from one domain to build a model for another domain. We propose the Variational Bi-domain Triplet Autoencoder (VBTA) that learns a joint distribution of objects from different domains. We extend the VBTAs objective function by the relative constraints or triplets that sampled from the shared latent space across domains. In other words, we combine the deep generative models with a metric learning ideas in order to improve the final objective with the triplets information. The performance of the VBTA model is demonstrated on different tasks: image-to-image translation, bi-directional image generation and cross-lingual document classification.
