Lifelong Generative Modeling

1 code implementation ICLR 2018 Jason Ramapuram, Magda Gregorova, Alexandros Kalousis

Lifelong learning is the problem of learning multiple consecutive tasks in a sequential manner, where knowledge gained from previous tasks is retained and used to aid future learning over the lifetime of the learner.

GrannGAN: Graph annotation generative adversarial networks

1 code implementation1 Dec 2022 Yoann Boget, Magda Gregorova, Alexandros Kalousis

The model we propose tackles the problem of generating the data features constrained by the specific graph structure of each data point by splitting the task into two phases.

Generative Adversarial Network Graph Matching

Learning Leading Indicators for Time Series Predictions

no code implementations7 Jul 2015 Magda Gregorova, Alexandros Kalousis, Stéphane Marchand-Maillet

We consider the problem of learning models for forecasting multiple time-series systems together with discovering the leading indicators that serve as good predictors for the system.

Permutation Equivariant Generative Adversarial Networks for Graphs

no code implementations7 Dec 2021 Yoann Boget, Magda Gregorova, Alexandros Kalousis

One solution consists of using equivariant generative functions, which ensure the ordering invariance.

Discrete Graph Auto-Encoder

no code implementations13 Jun 2023 Yoann Boget, Magda Gregorova, Alexandros Kalousis

Despite advances in generative methods, accurately modeling the distribution of graphs remains a challenging task primarily because of the absence of predefined or inherent unique graph representation.

Diffusion-based Visual Counterfactual Explanations -- Towards Systematic Quantitative Evaluation

1 code implementation11 Aug 2023 Philipp Vaeth, Alexander M. Fruehwald, Benjamin Paassen, Magda Gregorova

Latest methods for visual counterfactual explanations (VCE) harness the power of deep generative models to synthesize new examples of high-dimensional images of impressive quality.
