Local Wavelet Transform on a Helix Space Curve Based on Frenet Frame

Xiaohui Zhou, Jian Ying Zhu

Based on the Frenet frame, the approximate Local Wavelet Transform (LWT) is investigated on a class of generalized helix curves by their tangent projections at specific points. Initially, parametric equations are formulated for various types of helix curves, including circular helices and …

Deep Time Series Anomaly Detection with Local Temporal Pattern Learning

Yizhou Li, Yijie Wang, Hongzuo Xu, Xiaohui Zhou

Self-supervised time series anomaly detection (TSAD) demonstrates remarkable performance improvement by extracting high-level data semantics through proxy tasks. Nonetheless, most existing self-supervised TSAD techniques rely on manual- or neural-based transformations when designing proxy tasks, overlooking the intrinsic temporal patterns of time series. …

Self-organizing Competitive Neural Network Based Adaptive Sparse Representation for Magnetotelluric Data Denoising

Xiaoqiong Liu, Guang Li, Jin Li, Xiaohui Zhou et autres

Abstract The existing sparse decomposition denoising methods for magnetotelluric (MT) data need to set the iterative stop condition manually, which not only has a large workload and high difficulty, but also easily causes subjective bias. To this end, we propose a new …

Local-Adaptive Transformer for Multivariate Time Series Anomaly Detection and Diagnosis

Xiaohui Zhou, Yijie Wang, Hongzuo Xu, Ming-Yu Liu et autres

Time series data are pervasive in varied real-world applications, and accurately identifying anomalies in time series is of great importance. Many current methods are insufficient to model long-term dependence, whereas some anomalies can be only identified through long temporal contextual information. This …

Statistical analysis of ionospheric vertical total electron content anomalies before global Mw≥6.0 shallow earthquakes during 2000–2020

Yifang Ma, Xiaohui Zhou, Yilin Yang, Leyin Hu et autres

To quantitatively investigate the relationship between earthquakes and ionospheric anomalies, this paper presents a statistical study of pre-earthquake vertical total electron content (VTEC) variations. A total of 1522 shallow (≤60 km) strong (Mw≥6.0) earthquakes in the global area during 2000-2020 are selected, …
