Directly Forecasting Belief for Reinforcement Learning with Delays

ICML 2025poster

Reinforcement learning (RL) with delays is challenging as sensory perceptions lag behind the actual events: the RL agent needs to estimate the real state of its environment based on past observations. State-of-the-art (SOTA) methods typically employ recursive, step-by-step forecasting of states. Thi…

Landing-Aware Multi-Drone Routing in Last-Mile Delivery Services

IROS 2025

We propose a framework to compute the optimal routes for multi-drones to minimize the delivery time in the last-mile delivery service. We mainly focus on a notion of the landing exclusion zone that appears during the landing phase; an area around the drop-off site is blocked until a drop-off is comp

Boosting Reinforcement Learning with Strongly Delayed Feedback Through Auxiliary Short Delays

ICML 2024poster

Reinforcement learning (RL) is challenging in the common case of delays between events and their sensory perceptions. State-of-the-art (SOTA) state augmentation techniques either suffer from state space explosion or performance degeneration in stochastic environments. To address these challenges, we…

Variational Delayed Policy Optimization

NeurIPS 2024spotlight

In environments with delayed observation, state augmentation by including actions within the delay window is adopted to retrieve Markovian property to enable reinforcement learning (RL). Whereas, state-of-the-art (SOTA) RL techniques with Temporal-Difference (TD) learning frameworks commonly suffer…
