Breaking Boundaries: Balancing Performance and Robustness in Deep Wireless Traffic Forecasting

no code implementations16 Nov 2023 Romain Ilbert, Thai V. Hoang, Zonghua Zhang, Themis Palpanas

Our optimal model can retain up to $92. 02\%$ the performance of the original forecasting model in terms of Mean Squared Error (MSE) on clean data, while being more robust than the standard adversarially trained models on perturbed data.

Multivariate Time Series Anomaly Detection: Fancy Algorithms and Flawed Evaluation Methodology

1 code implementation24 Aug 2023 Mohamed El Amine Sehili, Zonghua Zhang

The main objective of this work is to stimulate more effort towards important aspects of the research such as data, experiment design, evaluation methodology and result interpretability, instead of putting the highest weight on the design of increasingly more complex and "fancier" algorithms.

Anomaly Detection Time Series +1

A Generic Approach to Integrating Time into Spatial-Temporal Forecasting via Conditional Neural Fields

no code implementations11 May 2023 Minh-Thanh Bui, Duc-Thinh Ngo, Demin Lu, Zonghua Zhang

Self-awareness is the key capability of autonomous systems, e. g., autonomous driving network, which relies on highly efficient time series forecasting algorithm to enable the system to reason about the future state of the environment, as well as its effect on the system behavior as time progresses.

Little Help Makes a Big Difference: Leveraging Active Learning to Improve Unsupervised Time Series Anomaly Detection

no code implementations25 Jan 2022 Hamza Bodor, Thai V. Hoang, Zonghua Zhang

Generally, unsupervised anomaly detection algorithms gain more popularity than the supervised ones, due to the fact that labeling KPIs is extremely time- and resource-consuming, and error-prone.

Active Learning Time Series +2

Anomalous Communications Detection in IoT Networks Using Sparse Autoencoders

no code implementations26 Dec 2019 Mustafizur Rahman Shahid, Gregory Blanc, Zonghua Zhang, Hervé Debar

A set of sparse autoencoders is then trained to learn the profile of the legitimate communications generated by an experimental smart home network.
