AI-assisted Automated Short Answer Grading of Handwritten University Level Mathematics Exams
Tianyi Liu, Julia Chatain, Laura Kobel-Keller +3
Effective and timely feedback in educational assessments is essential but labor-intensive, especially for complex tasks. Recent developments in automated feedback systems, ranging…
Taxonomy-Structured Domain Adaptation
Tianyi Liu, Zihao Xu, Hao He +3
Domain adaptation aims to mitigate distribution shifts among different domains. However, traditional formulations are mostly limited to categorical domains, greatly simplifying nua…
Tag-assisted Multimodal Sentiment Analysis under Uncertain Missing Modalities
Jiandian Zeng, Tianyi Liu, Jiantao Zhou
Multimodal sentiment analysis has been studied under the assumption that all modalities are available. However, such a strong assumption does not always hold in practice, and most…
Unified Multimodal Pre-training and Prompt-based Tuning for Vision-Language Understanding and Generation
Tianyi Liu, Zuxuan Wu, Wenhan Xiong +2
Most existing vision-language pre-training methods focus on understanding tasks and use BERT-like objectives (masked language modeling and image-text matching) during pretraining.…
Regularized Attentive Capsule Network for Overlapped Relation Extraction
Tianyi Liu, Xiangyu Lin, Weijia Jia +2
Distantly supervised relation extraction has been widely applied in knowledge base construction due to its less requirement of human efforts. However, the automatically established…
Neural Relation Extraction via Inner-Sentence Noise Reduction and Transfer Learning
Tianyi Liu, Xinsong Zhang, Wanhao Zhou +1
Extracting relations is critical for knowledge base completion and construction in which distant supervised methods are widely used to extract relational facts automatically with t…
