One Train for Two Tasks: An Encrypted Traffic Classification Framework Using Supervised Contrastive Learning

1 code implementation12 Feb 2024 Haozhen Zhang, Xi Xiao, Le Yu, Qing Li, Zhen Ling, Ye Zhang

In particular, we utilize supervised contrastive learning to enhance the packet-level and flow-level representations and perform graph data augmentation on the byte-level traffic graph so that the fine-grained semantic-invariant characteristics between bytes can be captured through contrastive learning.

Time-aware Graph Structure Learning via Sequence Prediction on Temporal Graphs

1 code implementation13 Jun 2023 Haozhen Zhang, Xueting Han, Xi Xiao, Jing Bai

To address these issues, we propose a Time-aware Graph Structure Learning (TGSL) approach via sequence prediction on temporal graphs, which learns better graph structures for downstream tasks through adding potential temporal edges.

SE-ECGNet: A Multi-scale Deep Residual Network with Squeeze-and-Excitation Module for ECG Signal Classification

1 code implementation10 Dec 2020 Haozhen Zhang, Wei Zhao, Shuang Liu

The classification of electrocardiogram (ECG) signals, which takes much time and suffers from a high rate of misjudgment, is recognized as an extremely challenging task for cardiologists.
