Continuous Actions from Discrete Minds: Latent-Aligned Planning for End-to-End Autonomous Driving

The paper introduces LaPla, a Vision‑Language‑Action framework that uses a latent‑aligned planning approach to convert discrete semantic reasoning into continuous, physics‑constrained driving actions. It employs a residual VQ‑VAE to encode vehicle kinematics into a structured latent space, then projects multimodal inputs—images, past actions, and text—directly into this latent space, allowing a frozen decoder to generate physically plausible trajectories without quantization errors. Experiments on nuScenes and NVIDIA AlpaSim show LaPla reduces long‑horizon L2 error by 15.52% and improves closed‑loop success rates by 33.34 percentage points while cutting inference latency.

RotVLA: Rotational Latent Action for Vision-Language-Action Model

RotVLA introduces a Vision‑Language‑Action framework that replaces discrete latent action encoding with a continuous rotational latent action representation on the group SO(n). This design provides continuity, compositionality, and structured geometry that better capture real‑world action dynamics, and a triplet frame learning scheme enforces meaningful temporal dynamics while preventing degeneration. Trained with 1.7 B parameters on large cross‑embodiment datasets, RotVLA achieves state‑of‑the‑art performance on LIBERO and RoboTwin2.0 benchmarks and shows strong real‑world manipulation results.

ReMoMask-2: Latent Retrieval-Augmented Masked Motion Generation

ReMoMask-2 is a retrieval‑augmented text‑to‑motion generation framework that improves on complex motion descriptions by addressing coarse retrieval and representation gaps. It introduces a structure‑aware RAG pipeline with Hierarchical Bidirectional Momentum contrastive learning, Semantic Spatial‑Temporal Attention, and Topology Structured Masking, and rebuilds the retrieval database in the generator’s latent space using a lightweight projector. Experiments on HumanML3D, KIT‑ML, and SnapMoGen show state‑of‑the‑art retrieval accuracy and the lowest FID scores, with a single mask‑transformer stage delivering faster inference than the previous two‑stage design.

ZYT-World: A Real-Time Controllable World Model for Closed-Loop Autonomous-Driving Simulation

ZYT-World is a real‑time, controllable world model designed for closed‑loop autonomous‑driving simulation. It generates a full fisheye‑pinhole camera rig at native resolution, using Plucker adapters for camera geometry, ego‑motion adaptive layer normalization for motion control, and a lightweight pixel‑aligned layout to condition traffic participants. The model achieves high fidelity to a 40‑step teacher while being over 100 times faster, and includes an implicit‑memory module that preserves place‑specific evidence for long‑horizon stability.
