Low-resource Taxonomy Enrichment with Pretrained Language Models

no code implementations EMNLP 2021 Kunihiro Takeoka, Kosuke Akimoto, Masafumi Oyamada

Conventional supervised methods for this enrichment task fail to find optimal parents of new terms in low-resource settings where only small taxonomies are available because of overfitting to hierarchical relationships in the taxonomies.

Context Quality Matters in Training Fusion-in-Decoder for Extractive Open-Domain Question Answering

no code implementations21 Mar 2024 Kosuke Akimoto, Kunihiro Takeoka, Masafumi Oyamada

Finally, based on these observations, we propose a method to mitigate overfitting to specific context quality by introducing bias to the cross-attention distribution, which we demonstrate to be effective in improving the performance of FiD models on different context quality.
