Dynamic Schema Graph Fusion Network for Multi-Domain Dialogue State Tracking

no code implementations • ACL 2022 • Yue Feng, Aldo Lipani, Fanghua Ye, Qiang Zhang, Emine Yilmaz

Existing approaches that have considered such relations generally fall short in: (1) fusing prior slot-domain membership relations and dialogue-aware dynamic slot relations explicitly, and (2) generalizing to unseen domains.

ASSIST: Towards Label Noise-Robust Dialogue State Tracking

1 code implementation • Findings (ACL) 2022 • Fanghua Ye, Yue Feng, Emine Yilmaz

In this paper, instead of improving the annotation quality further, we propose a general framework, named ASSIST (lAbel noiSe-robuSt dIalogue State Tracking), to train DST models robustly from noisy labels.

MultiWOZ 2.4: A Multi-Domain Task-Oriented Dialogue Dataset with Essential Annotation Corrections to Improve State Tracking Evaluation

1 code implementation • 1 Apr 2021 • Fanghua Ye, Jarana Manotumruksa, Emine Yilmaz

This work introduces MultiWOZ 2. 4, in which we refine all annotations in the validation set and test set on top of MultiWOZ 2. 1.

Auto-weighted Robust Federated Learning with Corrupted Data Sources

1 code implementation • 14 Jan 2021 • Shenghui Li, Edith Ngai, Fanghua Ye, Thiemo Voigt

In this paper, we address this challenge by proposing Auto-weighted Robust Federated Learning (arfl), a novel approach that jointly learns the global model and the weights of local updates to provide robustness against corrupted data sources.

Unsupervised Few-Bits Semantic Hashing with Implicit Topics Modeling

1 code implementation • Findings of the Association for Computational Linguistics 2020 • Fanghua Ye, Jarana Manotumruksa, Emine Yilmaz

Semantic hashing is a powerful paradigm for representing texts as compact binary hash codes.

Outlier-Resilient Web Service QoS Prediction

1 code implementation • 1 Jun 2020 • Fanghua Ye, Zhiwei Lin, Chuan Chen, Zibin Zheng, Hong Huang

The proliferation of Web services makes it difficult for users to select the most appropriate one among numerous functionally identical or similar service candidates.

Deep Autoencoder-like Nonnegative Matrix Factorization for Community Detection

2 code implementations • CIKM 2018 • Fanghua Ye, Chuan Chen, Zibin Zheng

Considering the complicated and diversified topology structures of real-world networks, it is highly possible that the mapping between the original network and the community membership space contains rather complex hierarchical information, which cannot be interpreted by classic shallow NMF-based approaches.
