Towards Data-Free Domain Generalization

1 code implementation9 Oct 2021 Ahmed Frikha, Haokun Chen, Denis Krompaß, Thomas Runkler, Volker Tresp

In particular, we address the question: How can knowledge contained in models trained on different source domains be merged into a single model that generalizes well to unseen target domains, in the absence of source and target domain data?

Data-free Knowledge Distillation Domain Generalization

Discovery of New Multi-Level Features for Domain Generalization via Knowledge Corruption

no code implementations9 Sep 2021 Ahmed Frikha, Denis Krompaß, Volker Tresp

Machine learning models that can generalize to unseen domains are essential when applied in real-world scenarios involving strong domain shifts.

ARCADe: A Rapid Continual Anomaly Detector

1 code implementation10 Aug 2020 Ahmed Frikha, Denis Krompaß, Volker Tresp

Although continual learning and anomaly detection have separately been well-studied in previous works, their intersection remains rather unexplored.

Few-Shot One-Class Classification via Meta-Learning

1 code implementation8 Jul 2020 Ahmed Frikha, Denis Krompaß, Hans-Georg Köpken, Volker Tresp

Our experiments on eight datasets from the image and time-series domains show that our method leads to better results than classical OCC and few-shot classification approaches, and demonstrate the ability to learn unseen tasks from only few normal class samples.

Predicting the Co-Evolution of Event and Knowledge Graphs

no code implementations21 Dec 2015 Cristóbal Esteban, Volker Tresp, Yinchong Yang, Stephan Baier, Denis Krompaß

By predicting future events, we also predict likely changes in the knowledge graph and thus obtain a model for the evolution of the knowledge graph as well.

Learning with Memory Embeddings

no code implementations25 Nov 2015 Volker Tresp, Cristóbal Esteban, Yinchong Yang, Stephan Baier, Denis Krompaß

We introduce a number of hypotheses on human memory that can be derived from the developed mathematical models.

Type-Constrained Representation Learning in Knowledge Graphs

no code implementations11 Aug 2015 Denis Krompaß, Stephan Baier, Volker Tresp

Latent variable models have increasingly gained attention for the statistical modeling of knowledge graphs, showing promising results in tasks related to knowledge graph completion and cleaning.
