Don’t Trade Off Safety: Diffusion Regularization for Constrained Offline RL

NeurIPS 2025poster

Constrained reinforcement learning (RL) seeks high-performance policies under safety constraints. We focus on an offline setting where the agent learns from a fixed dataset—a common requirement in realistic tasks to prevent unsafe exploration. To address this, we propose Diffusion-Regularized Constr…

HS-FPN: High Frequency and Spatial Perception FPN for Tiny Object Detection

AAAI 2025technical

The introduction of Feature Pyramid Network (FPN) has significantly improved object detection performance. However, substantial challenges remain in detecting tiny objects, as their features occupy only a very small proportion of the feature maps. Although FPN integrates multi-scale features, it doe…
