DA-RL: decoupled attention-enhanced visual feature reinforcement learning for optimised decision-making in cyber-physical systems

In dynamic and complex environments, visual reinforcement learning (Visual RL) agents struggle to extract task-relevant information, achieve stable policy optimisation, and generalise across changing conditions. This paper proposes DA-RL, an attention-enhanced and decoupled reinf...

TPE-optimized XGBoost model for fine–grained prediction of tertiary vocational college students’ employment destinations

Predicting tertiary vocational college students’ employment destinations has become an urgent need for most tertiary vocational colleges. This study proposes a machine learning framework based on Tree-structured Parzen Estimator (TPE)-Optimized eXtreme gradient boosting (XGBoost)...
