Recently, I got many questions about the role of neural language models in #AI (due to our new OpenGPT-X project) and decided to write a blog post on the topic: jens-lehmann.org/blog/neural… #languagemodels #gpt3 #ArtificialIntelligence #OpenGPTX

In arxiv.org/abs/2105.12524, we (1) show that common benchmarks for knowledge graph embeddings and link prediction contain out-of-vocabulary entities and (2) provide improved datasets free of this limitation. Enjoy! #AI #KnowledgeGraph #MachineLearning @DiceResearch

Looks like complex spaces enjoy a convolution to achieve better embeddings. Our approach ConEx achieves nice results on benchmarks with a comparatively small number of parameters. More at github.com/dice-group/Convol… @_CaglarDemir #OpenScience #KnowledgeGraph #machinelearning
