Pruning detrimental LoRA modules can lead to substantial performance gains in multi-task models, challenging the assumption that all components contribute positively.

DriveFix tackles the "shaky camera" problem in 4D driving scene reconstruction, producing significantly more stable and coherent novel views by explicitly modeling spatio-temporal dependencies.

Achieve diffusion-level perceptual quality in monocular depth estimation at 40x the speed, by replacing the slow initial diffusion steps with a fast ViT-based depth map and refining in a compact latent space.

Achieve faithful textile pattern generation by disentangling clothing features and guiding a diffusion model with fine-grained alignment, outperforming existing image-to-image methods.

Ditch the min-max: Fuz-RL offers a fuzzy-measure guided approach to safe RL that achieves distributional robustness without complex optimization.

VLMs still can't reason about spatial logic in real-world scenes, but a new benchmark and scene graph method shows how to make progress.
