Finite-Time Event-Triggered Optimal Tracking Control for Strict-Feedback Nonlinear Systems With Input Delay via Reinforcement Learning

An online optimization algorithm is developed to achieve practical finite-time optimal tracking, where a finite-time actor–critic law is introduced to inject the same error-dependent evaluative term into both networks, rendering the weight misalignment dynamics finite-time stable without persistence of excitation and a...

FSCM-Net: Frequency-Spatial Collaborative Modeling for Traffic Scene Semantic Segmentation

To address the challenges of insufficient global semantic modeling and blurred boundaries in urban traffic scene segmentation, this study proposes a frequency-spatial collaborative framework based on DeepLabV3+. A Spectral Decoupling Adaptive Modulation (SDAM) module enhances low-frequency semantics and high-frequency...
