Efficient Bilingual Generalization from Neural Transduction Grammar Induction

no code implementations EMNLP (IWSLT) 2019 Yuchen Yan, Dekai Wu, Serkan Kumyol

We introduce (1) a novel neural network structure for bilingual modeling of sentence pairs that allows efficient capturing of bilingual relationship via biconstituent composition, (2) the concept of neural network biparsing, which applies to not only machine translation (MT) but also to a variety of other bilingual research areas, and (3) the concept of a biparsing-backpropagation training loop, which we hypothesize that can efficiently learn complex biparse tree patterns.

Noisy Positive-Unlabeled Learning with Self-Training for Speculative Knowledge Graph Reasoning

no code implementations13 Jun 2023 Ruijie Wang, Baoyu Li, Yichen Lu, Dachun Sun, Jinning Li, Yuchen Yan, Shengzhong Liu, Hanghang Tong, Tarek F. Abdelzaher

State-of-the-art methods fall short in the speculative reasoning ability, as they assume the correctness of a fact is solely determined by its presence in KG, making them vulnerable to false negative/positive issues.
