Foundational Inference Models for Dynamical Systems

no code implementations12 Feb 2024 Patrick Seifner, Kostadin Cvejoski, Ramses J. Sanchez

The resulting models, which we call foundational inference models (FIM), can be (i) copied and matched along the time dimension to increase their resolution; and (ii) copied and composed to build inference models of any dimensionality, without the need of any finetuning.

Neural Markov Jump Processes

Markov jump processes are continuous-time stochastic processes with a wide range of applications in both natural and social sciences.

Dynamic Review-based Recommenders

no code implementations27 Oct 2021 Kostadin Cvejoski, Ramses J. Sanchez, Christian Bauckhage, Cesar Ojeda

In the present work we leverage the known power of reviews to enhance rating predictions in a way that (i) respects the causality of review generation and (ii) includes, in a bidirectional fashion, the ability of ratings to inform language review models and vice-versa, language representations that help predict ratings end-to-end.

Recurrent Point Review Models

1 code implementation10 Dec 2020 Kostadin Cvejoski, Ramses J. Sanchez, Bogdan Georgiev, Christian Bauckhage, Cesar Ojeda

Specifically, we use the dynamic representations of recurrent point process models, which encode the history of how business or service reviews are received in time, to generate instantaneous language models with improved prediction capabilities.
