Uncertainty-oriented Order Learning for Facial Beauty Prediction

no code implementations1 Sep 2024 Xuefeng Liang, Zhenyou Liu, Jian Lin, XiaoHui Yang, Takatsune Kumada

To address these issues, we propose a new Uncertainty-oriented Order Learning (UOL), where the order learning addresses the inconsistency of FB standards by learning the FB order relations among face images rather than a mapping, and the uncertainty modeling represents the inconsistency in human cognition.

WeKnow-RAG: An Adaptive Approach for Retrieval-Augmented Generation Integrating Web Search and Knowledge Graphs

no code implementations14 Aug 2024 Weijian Xie, Xuefeng Liang, Yuhui Liu, Kaihua Ni, Hong Cheng, Zetian Hu

First, the accuracy and reliability of LLM responses are improved by combining the structured representation of Knowledge Graphs with the flexibility of dense vector retrieval.

Triple Disentangled Representation Learning for Multimodal Affective Analysis

no code implementations29 Jan 2024 Ying Zhou, Xuefeng Liang, Han Chen, Yin Zhao, Xin Chen, Lida Yu

We revisit the disentanglement issue, and propose a novel triple disentanglement approach, TriDiRA, which disentangles the modality-invariant, effective modality-specific and ineffective modality-specific representations from input data.

Learning Subjective Time-Series Data via Utopia Label Distribution Approximation

no code implementations15 Jul 2023 Wenxin Xu, Hexin Jiang, Xuefeng Liang, Ying Zhou, Yin Zhao, Jie Zhang

In this work, we propose Utopia Label Distribution Approximation (ULDA) for time-series data, which makes the training label distribution closer to real-world but unknown (utopia) label distribution.

Gaussian-smoothed Imbalance Data Improves Speech Emotion Recognition

no code implementations17 Feb 2023 Xuefeng Liang, Hexin Jiang, Wenxin Xu, Ying Zhou

We find the data distribution in the IEMOCAP dataset is very imbalanced, which may harm models to learn a better representation.

Tripartite: Tackle Noisy Labels by a More Precise Partition

no code implementations19 Feb 2022 Xuefeng Liang, Longshan Yao, Xingyu Liu, Ying Zhou

Instead, we propose a Tripartite solution to partition training data more precisely into three subsets: hard, noisy, and clean.

Unsupervised Outlier Detection using Memory and Contrastive Learning

no code implementations27 Jul 2021 Ning Huyan, Dou Quan, Xiangrong Zhang, Xuefeng Liang, Jocelyn Chanussot, Licheng Jiao

Instead, we think outlier detection can be done in the feature space by measuring the feature distance between outliers and inliers.

Happy Travelers Take Big Pictures: A Psychological Study with Machine Learning and Big Data

no code implementations22 Sep 2017 Xuefeng Liang, Lixin Fan, Yuen Peng Loh, Yang Liu, Song Tong

In psychology, theory-driven researches are usually conducted with extensive laboratory experiments, yet rarely tested or disproved with big data.
