Memorization-Dilation: Modeling Neural Collapse Under Label Noise

1 code implementation11 Jun 2022 Duc Anh Nguyen, Ron Levie, Julian Lienen, Gitta Kutyniok, Eyke Hüllermeier

The notion of neural collapse refers to several emergent phenomena that have been empirically observed across various canonical classification problems.

Conformal Credal Self-Supervised Learning

1 code implementation30 May 2022 Julian Lienen, Caglar Demir, Eyke Hüllermeier

One such method, so-called credal self-supervised learning, maintains pseudo-supervision in the form of sets of (instead of single) probability distributions over labels, thereby allowing for a flexible yet uncertainty-aware labeling.

Kronecker Decomposition for Knowledge Graph Embeddings

1 code implementation13 May 2022 Caglar Demir, Julian Lienen, Axel-Cyrille Ngonga Ngomo

Our experiments suggest that applying Kronecker decomposition on embedding matrices leads to an improved parameter efficiency on all benchmark datasets.

Credal Self-Supervised Learning

1 code implementation NeurIPS 2021 Julian Lienen, Eyke Hüllermeier

In our approach, we therefore allow the learner to label instances in the form of credal sets, that is, sets of (candidate) probability distributions.
