Latent Neural ODEs with Sparse Bayesian Multiple Shooting

1 code implementation7 Oct 2022 Valerii Iakovlev, Cagatay Yildiz, Markus Heinonen, Harri Lähdesmäki

Training dynamic models, such as neural ODEs, on long trajectories is a hard problem that requires using various tricks, such as trajectory splitting, to make model training work in practice.

ODE2VAE: Deep generative second order ODEs with Bayesian neural networks

1 code implementation NeurIPS 2019 Cagatay Yildiz, Markus Heinonen, Harri Lahdesmaki

We present Ordinary Differential Equation Variational Auto-Encoder (ODE2VAE), a latent second order ODE model for high-dimensional sequential data.

Learning Stochastic Differential Equations With Gaussian Processes Without Gradient Matching

1 code implementation16 Jul 2018 Cagatay Yildiz, Markus Heinonen, Jukka Intosalmi, Henrik Mannerström, Harri Lähdesmäki

We introduce a novel paradigm for learning non-parametric drift and diffusion functions for stochastic differential equation (SDE).

Gaussian Processes

Asynchronous Stochastic Quasi-Newton MCMC for Non-Convex Optimization

no code implementations ICML 2018 Umut Simsekli, Cagatay Yildiz, Than Huy Nguyen, Taylan Cemgil, Gael Richard

The results support our theory and show that the proposed algorithm provides a significant speedup over the recently proposed synchronous distributed L-BFGS algorithm.
