Anomaly Detection of Time Series with Smoothness-Inducing Sequential Variational Auto-Encoder

no code implementations2 Feb 2021 Longyuan Li, Junchi Yan, Haiyang Wang, Yaohui Jin

Our model is based on Variational Auto-Encoder (VAE), and its backbone is fulfilled by a Recurrent Neural Network to capture latent temporal structures of time series for both generative model and inference model.

Learning Interpretable Deep State Space Model for Probabilistic Time Series Forecasting

no code implementations31 Jan 2021 Longyuan Li, Junchi Yan, Xiaokang Yang, Yaohui Jin

We propose a deep state space model for probabilistic time series forecasting whereby the non-linear emission model and transition model are parameterized by networks and the dependency is modeled by recurrent neural nets.
