Add and Thin: Diffusion for Temporal Point Processes

no code implementations NeurIPS 2023 David Lüdke, Marin Biloš, Oleksandr Shchur, Marten Lienen, Stephan Günnemann

Autoregressive neural networks within the temporal point process (TPP) framework have become the standard for modeling continuous-time event data.

Neural Temporal Point Processes: A Review

no code implementations8 Apr 2021 Oleksandr Shchur, Ali Caner Türkmen, Tim Januschowski, Stephan Günnemann

Temporal point processes (TPP) are probabilistic generative models for continuous-time event sequences.

Point Processes

Fast and Flexible Temporal Point Processes with Triangular Maps

1 code implementation NeurIPS 2020 Oleksandr Shchur, Nicholas Gao, Marin Biloš, Stephan Günnemann

Temporal point process (TPP) models combined with recurrent neural networks provide a powerful framework for modeling continuous-time event data.

Intensity-Free Learning of Temporal Point Processes

3 code implementations ICLR 2020 Oleksandr Shchur, Marin Biloš, Stephan Günnemann

The standard way of learning in such models is by estimating the conditional intensity function.

Pitfalls of Graph Neural Network Evaluation

2 code implementations14 Nov 2018 Oleksandr Shchur, Maximilian Mumme, Aleksandar Bojchevski, Stephan Günnemann

We perform a thorough empirical evaluation of four prominent GNN models and show that considering different splits of the data leads to dramatically different rankings of models.

Dual-Primal Graph Convolutional Networks

no code implementations3 Jun 2018 Federico Monti, Oleksandr Shchur, Aleksandar Bojchevski, Or Litany, Stephan Günnemann, Michael M. Bronstein

In recent years, there has been a surge of interest in developing deep learning methods for non-Euclidean structured data such as graphs.

NetGAN: Generating Graphs via Random Walks

2 code implementations ICML 2018 Aleksandar Bojchevski, Oleksandr Shchur, Daniel Zügner, Stephan Günnemann

NetGAN is able to produce graphs that exhibit well-known network patterns without explicitly specifying them in the model definition.
