And finally #3
🔨 Rank bottlenecks in KGEs:
At Friday's "Salon des Refuses" I will present @sbadredd's new work on how rank bottlenecks limit knowledge graph embeddings

@luislamb We're glad to announce the NeSy 2025 Test of Time award for "Probabilistic Inference Modulo Theories"!
🏆Rodrigo de Salvo Braz was here to accept the award.
This is groundwork for recent NeSy approaches like DeepSeaProbLog and the probabilistic algebraic layer.
🎉Check our IJCAI'25 paper on #Explainable link prediction in #KG🔗
We use a path-based #RL model to generate explanations for predictions, rewarding paths that explain best ✨
And we've got user studies 🧑🔬
Great work led by Susana Nunes & @CPesquita👏

@orionweller In our work, we address this using a Mixture-of-Softmaxes output layer to score and rank concepts, breaking the bottleneck. We wonder if this could be a promising direction for the retrieval tasks you highlight as well. Great to see this parallel exploration! @EmilevanKrieken

@deedydas Insightful! We tackled the same problem in Knowledge Graph Completion. Dot-product scoring on low-dim embeddings severely limits what a model can predict. We call this a “rank bottleneck” to align with the existing LM literature. Our paper for context: https://t.co/IePSDw9VYb
I had the chance to visit @CPesquita group, hear more about their AI for Science projects and visit sunny Lisbon for a few days. Thanks for the warm welcome!
This week, we were very proud to host three brilliant young researchers: @sbadredd, Christoph Wehner and @olgamshk. They gave super interesting talks and engaged in inspiring discussions with our PhD students. Thank you for visiting! @lasige
Very excited to be in Barcelona for NeSy 2024!
We're presenting two papers:
- Our ICML paper https://t.co/GTW8OghshB
- A preview of our new NeSy library ULLER together with @sbadredd, @e_giunchiglia and Robin Manhaeve. We will give a special tutorial on Thursday!
Hit me up!
