Deep Time Series Anomaly Detection with Local Temporal Pattern Learning

ICASSP 2025accepted

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, ove…

CFDNet: A Generalizable Foggy Stereo Matching Network with Contrastive Feature Distillation

ICRA 2024poster

Stereo matching under foggy scenes remains a challenging task since the scattering effect degrades the visibility and results in less distinctive features for dense correspondence matching. While some previous learning-based methods integrated a physical scattering function for simultaneous stereo-m…

Fden: Mining Effective Information of Features in Detecting Network Anomalies

ICASSP 2021accepted

Network anomaly detection is important for detecting and reacting to the presence of network attacks. In this paper, we propose a novel method to effectively leverage the features in detecting network anomalies, named FDEn, consisting of flow-based Feature Derivation (FD) and prior knowledge incorpo…
