Micro-expression Detection based on Action Units and Multi-region Feature Fusion

2022

Recently, micro-expression detection has attracted much attention, since micro-expression has potential lie detection applications. In this paper, a micro-expression detection algorithm based on action units (AUs) and multi-region feature fusion is proposed. First, the regions …

Contrastive learning with hybrid data augmentation and pseudo-label supervision for short text clustering

2026 · Intelligent Data Analysis

Contrastive learning has become a powerful paradigm for unsupervised representation learning. However, its effectiveness largely depends on carefully designed data augmentation strategies to generate meaningful positive and negative pairs. Additionally, unsupervised clustering algorithms are typically …
