Graph Neural Networks for Microbial Genome Recovery

no code implementations26 Apr 2022 Andre Lamurias, Alessandro Tibo, Katja Hose, Mads Albertsen, Thomas Dyhre Nielsen

In this paper, we propose to use Graph Neural Networks (GNNs) to leverage the assembly graph when learning contig representations for metagenomic binning.

Federated Data Science to Break Down Silos [Vision]

no code implementations25 Nov 2021 Essam Mansour, Kavitha Srinivas, Katja Hose

Similar to Open Data initiatives, data science as a community has launched initiatives for sharing not only data but entire pipelines, derivatives, artifacts, etc.

MindReader: Recommendation over Knowledge Graph Entities with Explicit User Ratings

1 code implementation8 Jun 2021 Anders H. Brams, Anders L. Jakobsen, Theis E. Jendal, Matteo Lissandrini, Peter Dolog, Katja Hose

As a demonstration of the importance of this new dataset, we present a comparative study of the effect of the inclusion of ratings on non-item KG entities in a variety of state-of-the-art recommendation models.
