SVGL: Scale-Variable Graph Learning in Model Space for Multivariate Time Series Classification

AAAI 2026technical

Multivariate time series classification (MTSC) has broad applications in numerous domains. Existing MTSC methods typically focus on either temporal dynamics or variable interactions of the data, often overlooking cross-scale couplings among different variables. To bridge this gap, we propose Scale-V

Inside and Inside: Efficient Anomaly Detection by Fully Capturing the Detailed Dynamics

ICASSP 2025accepted

Anomaly detection in sequential signals is gaining prominence, especially with limited training data and timeliness requirements. Fully extracting the data-inside changing information, we propose a novel Wavelet-Enhanced Reservoir Computing framework (WE-Res). Our framework uses Discrete Wavelet Tra…

Learning in the Model Space: Fault Diagnosis by Co-objective Learning in DynInt Model Space

ICASSP 2025accepted

Fault Diagnosis (FD) in time-varying systems faces challenges like limited training data, varying environments, and timeliness. Building upon the framework of model-space learning (MSL), we introduce co-objective learning in Dynamic-Integration network (DynInt) model space as a solution for FD. MSL…

ND-SDF: Learning Normal Deflection Fields for High-Fidelity Indoor Reconstruction

ICLR 2025spotlight

Neural implicit reconstruction via volume rendering has demonstrated its effectiveness in recovering dense 3D surfaces. However, it is non-trivial to simultaneously recover meticulous geometry and preserve smoothness across regions with differing characteristics. To address this issue, previous meth…
