Beyond Looking Up, Try Looking Around: Harmonizing Global Structure and Local Consistency in Optimal Transport for Short Text Clustering
Zhihao Yao, Yuxuan Gu, Jixuan Yin +1
Pseudo-labeling based on Optimal Transport (OT) has become an effective mechanism for enhancing short text clustering. Existing OT methods are short in modeling semantic consistenc…
IOCC: Aligning Semantic and Cluster Centers for Few-shot Short Text Clustering
Zhihao Yao
In clustering tasks, it is essential to structure the feature space into clear, well-separated distributions. However, because short text representations have limited expressivenes…
Adaptive Backtracking for Privacy Protection in Large Language Models
Zhihao Yao, Yuxuan Gu, Xiachong Feng +3
The preservation of privacy has emerged as a critical topic in the era of artificial intelligence. However, current work focuses on user-oriented privacy, overlooking severe enterp…
Reliable Pseudo-labeling via Optimal Transport with Attention for Short Text Clustering
Zhihao Yao
Short text clustering has gained significant attention in the data mining community. However, the limited valuable information contained in short texts often leads to low-discrimin…
