Global Safe Sequential Learning via Efficient Knowledge Transfer

1 code implementation22 Feb 2024 Cen-You Li, Olaf Duennbier, Marc Toussaint, Barbara Rakitsch, Christoph Zimmer

As transferable source knowledge is often available in safety critical experiments, we propose to consider transfer safe sequential learning to accelerate the learning of safety.

Hybrid Modeling Design Patterns

no code implementations29 Dec 2023 Maja Rudolph, Stefan Kurz, Barbara Rakitsch

In this paper, we provide four base patterns that can serve as blueprints for combining data-driven components with domain knowledge into a hybrid approach.

Sampling-Free Probabilistic Deep State-Space Models

no code implementations15 Sep 2023 Andreas Look, Melih Kandemir, Barbara Rakitsch, Jan Peters

Many real-world dynamical systems can be described as State-Space Models (SSMs).

Cheap and Deterministic Inference for Deep State-Space Models of Interacting Dynamical Systems

1 code implementation2 May 2023 Andreas Look, Melih Kandemir, Barbara Rakitsch, Jan Peters

Furthermore, we propose structured approximations to the covariance matrices of the Gaussian components in order to scale up to systems with many agents.

Combining Slow and Fast: Complementary Filtering for Dynamics Learning

no code implementations27 Feb 2023 Katharina Ensinger, Sebastian Ziesche, Barbara Rakitsch, Michael Tiemann, Sebastian Trimpe

This filtering technique combines two signals by applying a high-pass filter to one signal, and low-pass filtering the other.

Learning Interacting Dynamical Systems with Latent Gaussian Process ODEs

1 code implementation24 May 2022 Çağatay Yıldız, Melih Kandemir, Barbara Rakitsch

We study time uncertainty-aware modeling of continuous-time dynamics of interacting objects.

Traversing Time with Multi-Resolution Gaussian Process State-Space Models

no code implementations6 Dec 2021 Krista Longi, Jakob Lindinger, Olaf Duennbier, Melih Kandemir, Arto Klami, Barbara Rakitsch

These models have a natural interpretation as discretized stochastic differential equations, but inference for long sequences with fast and slow transitions is difficult.

Learning Partially Known Stochastic Dynamics with Empirical PAC Bayes

no code implementations17 Jun 2020 Manuel Haussmann, Sebastian Gerwinn, Andreas Look, Barbara Rakitsch, Melih Kandemir

Neural Stochastic Differential Equations model a dynamical environment with neural nets assigned to their drift and diffusion terms.

Time Series Prediction

A Deterministic Approximation to Neural SDEs

no code implementations16 Jun 2020 Andreas Look, Melih Kandemir, Barbara Rakitsch, Jan Peters

Our deterministic approximation of the transition kernel is applicable to both training and prediction.
