Deep dynamic factor models

WebMay 11, 2024 · However, it is frequently observed that these models do not perform well for complex systems and they are not applicable to time-series data. Therefore, we propose a generative model based on variational autoencoder and recurrent neural network to infer the latent dynamic factors for multivariate timeseries data. This approach allows us to ... WebJan 29, 2024 · This paper generalises dynamic factor models for multidimensional dependent data.
