摘要:

本文的贡献是双重的。首先,我们提出了ProbCast -一种新的概率模型的多变量时间序列预测。我们采用了一个条件GAN框架来训练我们的模型与对抗训练。其次,我们提出了一个框架,让我们把一个确定性的模型转换成一个概率性的,具有更好的性能。该框架的动机是将现有的高精度点预测模型转换为它们的概率对应模型,或者通过仔细有效地选择GAN组件的架构来稳定地训练GANs。我们在两个公开的数据集上进行实验,即电力消费数据集和汇率数据集。实验结果表明,我们的模型的显着性能以及我们提出的框架的成功应用。

英文摘要:

The contribution of this paper is two-fold. First, we present ProbCast - a novel probabilistic model for multivariate time-series forecasting. We employ a conditional GAN framework to train our model with adversarial training. Second, we propose a framework that lets us transform a deterministic model into a probabilistic one with improved performance. The motivation of the framework is to either transform existing highly accurate point forecast models to their probabilistic counterparts or to train GANs stably by selecting the architecture of GAN's component carefully and efficiently. We conduct experiments over two publicly available datasets namely electricity consumption dataset and exchange-rate dataset. The results of the experiments demonstrate the remarkable performance of our model as well as the successful application of our proposed framework.
