FMMVCC: Fuzzy Mamba-based Multi-View Contrastive Clustering for Univariate Time Series
Summary
FMMVCC, a novel Mamba-based deep clustering framework, is introduced for univariate time series analysis, addressing the challenge of limited annotations in large time series datasets. This framework utilizes state space sequence modeling to efficiently capture long-range temporal dependencies with linear computational complexity, a significant improvement over existing deep clustering methods that often incur high costs. FMMVCC further integrates multi-view self-supervised learning, employing temporal masking and augmentations to enhance representation learning. Experimental evaluation across 15 benchmark datasets demonstrates FMMVCC's superior performance, consistently outperforming leading baselines. It achieved the best overall performance in 29 of 60 total metric evaluations and secured the highest average rank across all tested scenarios. The paper was published on 2026-07-08.
Key takeaway
For Machine Learning Engineers developing unsupervised clustering solutions for univariate time series, FMMVCC presents a compelling alternative to existing deep methods. You should consider integrating Mamba-based architectures for their linear complexity and superior handling of long-range dependencies. This framework's multi-view self-supervised learning approach, incorporating temporal masking, can significantly improve your model's ability to discover meaningful patterns in data with limited annotations.
