Hybrid AC/DC Distribution Network Planning Under Renewable Ramp Stress Considering Network-Constrained Flexibility via RL with Feasible Projection

High renewable energy penetration intensifies net-load ramping and increases the demand for operational flexibility in distribution networks. However, existing hybrid AC/DC distribution network planning studies rarely consider both renewable ramp stress and the network deliverability of available flexibility. Furthermo...

Electronic System-Level Optimization of Network Slicing and Resource Allocation for 6G URLLC Applications

In this paper, we propose a complete mathematical framework for optimizing network slicing and resource allocation at the electronic system-level (ESL) of 6G ultra-reliable low-latency communication (URLLC). We present a multi-dimensional, non-convex mixed-integer stochastic optimization problem that jointly optimizes...

Hybrid Path Planning and Reinforcement Learning-Based Magnetic Guidewire Navigation in Cardiac Intervention

Magnetically driven microrobots have shown significant potential in biomedical applications, including endovascular intervention, targeted therapy, and drug delivery, particularly in the treatment of cardiovascular diseases. Conventional vascular interventional procedures typically rely on physicians to manually manipu...

Adaptive Parallel-World Self-Rewarding and Cross-Model Mutual Rewarding for Large Language Models

Reward generation is a central component of reinforcement learning, preference optimization, and self-improvement in large language models (LLMs). Existing approaches have demonstrated that an LLM can evaluate its own outputs and use the resulting judgments to improve its behavior. However, self-rewarding systems may s...

Adaptive Switching Between Self-Reinforcement and Mutual Reinforcement Learning for Multiple Large Language Models

Large language models (LLMs) can generate candidate answers, evaluate their quality, and use evaluation signals to improve subsequent responses. However, self-evaluation may reinforce a model's own biases and errors, whereas evaluation by other models may introduce evaluator disagreement, capability mismatches, and cor...

Deep-Economic Dispatch: A Deep Reinforcement Learning Framework for Optimal Power Generation Scheduling in Real-Time Electricity Markets

The increasing complexity of real-time electricity markets and fluctuating load demands challenges traditional economic dispatch methods, which often fail to balance cost efficiency and system reliability. This study presents a Deep Reinforcement Learning (DRL) framework for real-time power dispatch, enabling adaptive...

AURA: Autonomous Urban Reconnaissance Array for Post-Earthquake Emergency Communication Networks

This paper presents AURA (Autonomous Urban Reconnaissance Array), a ROS 2-based drone swarm system designed to restore emergency WiFi communication in post-earthquake disaster zones. The system deploys five coordinated UAVs that autonomously establish a selfhealing mesh network. The architecture integrates PX4SITL with...

When Optimization Forgets the Minority: Bias Amplification in Policy-Gradient Reinforcement Learning

Bias amplification, the tendency of trained models to be more biased than the data that produced them, is well documented in supervised learning. We study it in policy-gradient reinforcement learning, where there is no static dataset: each episode belongs to a latent group that shapes the reward but is invisible to the...

Learning to Generalize Across Conditions: A PPO-Based Learning Approach to Multi-Condition Multi-Objective Optimization

This study introduces sPPO-CR, a policy-gradient deep reinforcement learning (DRL) algorithm for multi-objective (MO) and multi-condition multi-objective (MCMO) optimization. The method builds on a simplified single-step variant of Proximal Policy Optimization (PPO) and incorporates a Chebyshev-based reproduction mecha...
