Variational Augmented Invertible Koopman Autoencoder for probabilistic time series forecasting

Neural Koopman autoencoder models have been shown to successfully build a latent embedding with linear dynamics for arbitrary dynamical systems, enabling strong performance in long-term time series forecasting. However, these models usually work in a deterministic setting, which does not allow the quantification of the...

Discovering Data Manifold Geometry through Geometric Properties

An unsupervised objective is derived that learns structural properties of a representation map and theoretical results connecting its minimization to tangent-space recovery are established, while an autoencoder baseline shows that small map-first errors can still produce substantial violations of the targeted propertie...
