Multi-Resolution Dual-Branch DWT-MobileViT for Ultra-Lightweight Urban Noise Classification

Standard environmental sound classification frameworks compress 1D acoustic waveforms into 2D Mel-Spectrograms, discarding raw phase boundaries and flattening fine-grained temporal envelopes. Deep 2D convolutional networks struggle to isolate transient, pulsed mechanical sounds like jackhammers or vehicle horns in nois...

AIGS: Adaptive Incremental Gating System for Online Representation Learning in Non-Stationary Data Streams

Real-time data streams in Web of Things (WoT) and edge computing environments often evolve through latent regime changes. For online representation learning under strict computational constraints, the central problem is resolving the stability-plasticity dilemma: keeping useful historical knowledge while rapidly reacti...

Deployment-oriented evaluation of deep learning network intrusion detection systems

Future works require better cross-dataset testing, more evaluations of unseen attacks, and reliability checks in real-world secure communication environments, as well as joint evidence that the models can handle new attacks and new datasets while remaining reliable in IoT, IIoT, SDN, and future internet environments.
