DIVER: Reinforced Diffusion Breaks Imitation Bottlenecks in End-to-End Autonomous Driving

The introduction of FastBEV++ marks a significant advancement in camera-only Bird's-Eye-View (BEV) perception, addressing the challenges of balancing high performance with deployment efficiency. This framework utilizes a novel view transformation paradigm that simplifies the projection process, enabling effective execution with standard operator primitives.

A new approach called Future Temporal Knowledge Distillation (FTKD) has been introduced to enhance camera-based temporal 3D object detection, particularly in autonomous driving. This method allows online models to learn from future frames by transferring knowledge from offline models without strict frame alignment, thereby improving detection accuracy.

A novel approach to Full Surround Monocular Depth Estimation (FSMDE) has been introduced, addressing challenges such as high computational costs and difficulties in estimating metric-scale depth. This method employs a knowledge distillation strategy to transfer depth knowledge from a foundation model to a lightweight FSMDE network, enhancing real-time performance and scale consistency.

A novel training paradigm named FLARES has been introduced to enhance LiDAR multi-range semantic segmentation, addressing challenges related to the irregularity and sparsity of LiDAR data. This approach improves segmentation accuracy and computational efficiency by training with multiple range images derived from full point clouds, although it also introduces new challenges such as class imbalance and projection artifacts.

VG3T, a novel multi-view feed-forward network, has been introduced to enhance 3D scene representation from multi-view images by predicting a 3D semantic occupancy through a 3D Gaussian representation, addressing fragmentation issues seen in previous methods.

A new paradigm for autonomous driving has been proposed, introducing a spatial retrieval approach that utilizes offline geographic images, such as those from Google Maps, to enhance environmental perception. This method aims to address the limitations of existing systems that rely solely on onboard sensors, particularly in challenging conditions like darkness or occlusion.

NexusFlow has been introduced as a novel framework for Partially Supervised Multi-Task Learning (PS-MTL), which aims to unify diverse tasks under partial supervision using invertible flow networks. This approach addresses the challenge of learning from structurally different tasks while preserving information through bijective coupling layers, enabling effective knowledge transfer across tasks.

The introduction of DiffusionDriveV2 marks a significant advancement in reinforcement learning-constrained truncated diffusion modeling for end-to-end autonomous driving, addressing the limitations of its predecessor by enhancing output quality while maintaining multimodality. This model utilizes scale-adaptive multiplicative noise and intra-anchor GRPO for improved trajectory generation.
