Discovering Sounding Objects by Audio Queries for Audio Visual Segmentation

no code implementations18 Sep 2023 Shaofei Huang, Han Li, Yuqing Wang, Hongji Zhu, Jiao Dai, Jizhong Han, Wenge Rong, Si Liu

Explicit object-level semantic correspondence between audio and visual modalities is established by gathering object information from visual features with predefined audio queries.

Evaluating Open-Domain Dialogues in Latent Space with Next Sentence Prediction and Mutual Information

1 code implementation26 May 2023 Kun Zhao, Bohao Yang, Chenghua Lin, Wenge Rong, Aline Villavicencio, Xiaohui Cui

The long-standing one-to-many issue of the open-domain dialogues poses significant challenges for automatic evaluation methods, i. e., there may be multiple suitable responses which differ in semantics for a given conversational context.

Improving Variational Autoencoders with Density Gap-based Regularization

1 code implementation1 Nov 2022 Jianfei Zhang, Jun Bai, Chenghua Lin, Yanmeng Wang, Wenge Rong

There are effective ways proposed to prevent posterior collapse in VAEs, but we observe that they in essence make trade-offs between posterior collapse and hole problem, i. e., mismatch between the aggregated posterior distribution and the prior distribution.

Causal Intervention for Fairness in Multi-behavior Recommendation

no code implementations10 Sep 2022 Xi Wang, Wenjie Wang, Fuli Feng, Wenge Rong, Chuantao Yin

Specifically, we find that: 1) item popularity is a confounder between the exposed items and users' post-click interactions, leading to the first unfairness; and 2) some hidden confounders (e. g., the reputation of item producers) affect both item popularity and quality, resulting in the second unfairness.

Query-Response Interactions by Multi-tasks in Semantic Search for Chatbot Candidate Retrieval

no code implementations23 Aug 2022 Libin Shi, Kai Zhang, Wenge Rong

Semantic search for candidate retrieval is an important yet neglected problem in retrieval-based Chatbots, which aims to select a bunch of candidate responses efficiently from a large pool.

Enhancing Dual-Encoders with Question and Answer Cross-Embeddings for Answer Retrieval

no code implementations Findings (EMNLP) 2021 Yanmeng Wang, Jun Bai, Ye Wang, Jianfei Zhang, Wenge Rong, Zongcheng Ji, Shaojun Wang, Jing Xiao

To keep independent encoding of questions and answers during inference stage, variational auto-encoder is further introduced to reconstruct answers (questions) from question (answer) embeddings as an auxiliary task to enhance QA interaction in representation learning in training stage.

Similarity Based Auxiliary Classifier for Named Entity Recognition

1 code implementation IJCNLP 2019 Shiyuan Xiao, Yuanxin Ouyang, Wenge Rong, Jianxin Yang, Zhang Xiong

The segmentation problem is one of the fundamental challenges associated with name entity recognition (NER) tasks that aim to reduce the boundary error when detecting a sequence of entity words.

LSDSCC: a Large Scale Domain-Specific Conversational Corpus for Response Generation with Diversity Oriented Evaluation Metrics

no code implementations NAACL 2018 Zhen Xu, Nan Jiang, Bingquan Liu, Wenge Rong, Bowen Wu, Baoxun Wang, Zhuoran Wang, Xiaolong Wang

The experimental results have shown that our proposed corpus can be taken as a new benchmark dataset for the NRG task, and the presented metrics are promising to guide the optimization of NRG models by quantifying the diversity of the generated responses reasonably.
