Learning to Rank Visual Stories From Human Ranking Data

1 code implementation ACL 2022 Chi-Yang Hsu, Yun-Wei Chu, Vincent Chen, Kuan-Chieh Lo, Chacha Chen, Ting-Hao Huang, Lun-Wei Ku

In this paper, we present the VHED (VIST Human Evaluation Data) dataset, which first re-purposes human evaluation results for automatic evaluation; hence we develop Vrank (VIST Ranker), a novel reference-free VIST metric for story evaluation.

Only Send What You Need: Learning to Communicate Efficiently in Federated Multilingual Machine Translation

no code implementations15 Jan 2024 Yun-Wei Chu, Dong-Jun Han, Christopher G. Brinton

Federated learning (FL) is a promising approach for solving multilingual tasks, potentially enabling clients with their own language-specific data to collaboratively construct a high-quality neural machine translation (NMT) model.

Multi-Layer Personalized Federated Learning for Mitigating Biases in Student Predictive Analytics

no code implementations5 Dec 2022 Yun-Wei Chu, Seyyedali Hosseinalipour, Elizabeth Tenorio, Laura Cruz, Kerrie Douglas, Andrew Lan, Christopher Brinton

Traditional learning-based approaches to student modeling (e. g., predicting grades based on measured activities) generalize poorly to underrepresented/minority student groups due to biases in data availability.

Mitigating Biases in Student Performance Prediction via Attention-Based Personalized Federated Learning

no code implementations2 Aug 2022 Yun-Wei Chu, Seyyedali Hosseinalipour, Elizabeth Tenorio, Laura Cruz, Kerrie Douglas, Andrew Lan, Christopher Brinton

To learn better representations of student activity, we augment our approach with a self-supervised behavioral pretraining methodology that leverages multiple modalities of student behavior (e. g., visits to lecture videos and participation on forums), and include a neural network attention mechanism in the model aggregation stage.

Stretch-VST: Getting Flexible With Visual Stories

no code implementations ACL 2021 Chi-Yang Hsu, Yun-Wei Chu, Tsai-Lun Yang, Ting-Hao Huang, Lun-Wei Ku

Therefore, we propose to {``}stretch{''} the stories, which create the potential to present in-depth visual details.

MVIN: Learning Multiview Items for Recommendation

1 code implementation26 May 2020 Chang-You Tai, Meng-Ru Wu, Yun-Wei Chu, Shao-Yu Chu, Lun-Wei Ku

From the entity view, the mixing layer contrasts layer-wise GCN information to further obtain comprehensive features from internal entity-entity interactions in the KG.

Multi-step Joint-Modality Attention Network for Scene-Aware Dialogue System

no code implementations17 Jan 2020 Yun-Wei Chu, Kuan-Yen Lin, Chao-Chun Hsu, Lun-Wei Ku

Understanding dynamic scenes and dialogue contexts in order to converse with users has been challenging for multimodal dialogue systems.

GraphSW: a training protocol based on stage-wise training for GNN-based Recommender Model

1 code implementation13 Aug 2019 Chang-You Tai, Meng-Ru Wu, Yun-Wei Chu, Shao-Yu Chu

Recently, researchers utilize Knowledge Graph (KG) as side information in recommendation system to address cold start and sparsity issue and improve the recommendation performance.
