FQ-PETR: Fully Quantized Position Embedding Transformation for Multi-View 3D Object Detection

A new study introduces Semantic Orthogonal Calibration (SoC), a method aimed at improving the calibration of uncertainty estimates in vision-language models (VLMs) during test-time prompt tuning. This approach addresses the challenge of overconfidence in models by enforcing smooth prototype separation while maintaining semantic proximity.

A recent survey on learning-based Multi-View Stereo (MVS) techniques highlights the advancements in 3D reconstruction, which is crucial for applications such as Augmented and Virtual Reality, autonomous driving, and robotics. The study categorizes these methods into depth map-based, voxel-based, NeRF-based, and others, emphasizing the effectiveness of depth map-based approaches.

A new study proposes a unified PAC-Bayesian framework for norm-based generalization bounds, addressing the challenges of understanding deep neural networks' generalization behavior. The research reformulates the derivation of these bounds as a stochastic optimization problem over anisotropic Gaussian posteriors, aiming to enhance the practical relevance of the results.

A recent study has assessed the effectiveness of amortized inference in Bayesian statistics, particularly under varying signal-to-noise ratios and distribution shifts. This method leverages deep neural networks to streamline the inference process, allowing for significant computational savings compared to traditional Bayesian approaches that require extensive likelihood evaluations.

The landscape of video generation is evolving, transitioning from merely creating visually appealing clips to constructing interactive virtual environments that adhere to physical plausibility. This shift is highlighted in a recent survey that conceptualizes modern video foundation models as a combination of implicit world models and video renderers, enabling coherent visual reasoning and task planning.
