RelFlexformers enable flexible integrable 3D RPE in attention via NU-FFT, generalizing prior methods to heterogeneous token positions with O(L log L) complexity.
Introduces the first heterogeneous multi-source mmWave point cloud HAR dataset and DAP-Net architecture with Doppler reparameterization and text alignment for cross-source robustness.
A public benchmark dataset and competition results for 3D dental landmark detection from intraoral scans, with the top team reaching 0.91 rank score using a stratified transformer and DBSCAN.
LLaMA-Adapter turns frozen LLaMA 7B into a capable instruction follower using only 1.2M new parameters and zero-init attention, matching Alpaca while extending to image-conditioned reasoning on ScienceQA and COCO.
MAPR improves adversarial robustness in 3D point cloud networks by aligning latent predictions with intrinsic manifold geometry via curvature/diffusion features and a consistency loss.
Delaunay Canopy uses Delaunay graphs as a geometric prior with region-wise curvature scoring to reconstruct accurate building wireframes from sparse and noisy airborne LiDAR point clouds.
CLAMP pretrains 3D multi-view encoders with contrastive learning on point clouds and actions, then initializes diffusion policies for more sample-efficient fine-tuning on robotic tasks.
The CC-ISAC framework aligns camera visuals with radio echoes via cross-attention and fuses multimodal data to reduce beam steering overhead by 71% and tracking overhead by 1.69-11.15% on the DeepSense 6G dataset while preserving angular accuracy.
Automatically constructed mapping priors from sensor aggregation are integrated via the MPA3D framework to achieve state-of-the-art 3D detection results on the Waymo Open Dataset.
