摘要:

在许多科学问题中,如视频监控,现代基因组学和金融,数据通常是从不同的测量跨时间,表现出时间依赖的异质性。因此,重要的是不仅要集成来自多个源的数据(称为多视图数据),而且要纳入时间依赖性,以便深入理解底层系统。我们提出了一个基于变分自动编码器和递归神经网络的生成模型来推断多视图时态数据的潜在动态。这种方法使我们能够在考虑时间因素的同时识别跨视图的未纠缠的潜在嵌入。我们调用我们提出的模型分析三个数据集上,我们证明了模型的有效性和可解释性。

英文摘要:

In many scientific problems such as video surveillance, modern genomics, and finance, data are often collected from diverse measurements across time that exhibit time-dependent heterogeneous properties. Thus, it is important to not only integrate data from multiple sources (called multi-view data), but also to incorporate time dependency for deep understanding of the underlying system. We propose a generative model based on variational autoencoder and a recurrent neural network to infer the latent dynamics for multi-view temporal data. This approach allows us to identify the disentangled latent embeddings across views while accounting for the time factor. We invoke our proposed model for analyzing three datasets on which we demonstrate the effectiveness and the interpretability of the model.
