MHeatmap: Two-Walk Laplacian Reordering and Mosaic Layout for Rectangular Matrix Visualization
Juntang Wang, Sheng'en Li, Liming Zhu +6
Weighted rectangular matrices record relations between two types of objects, such as occupations and industries, documents and terms, origins and destinations, or annotated classes…
DriftNeRF: Cross-Ray Density Drifting for Sparse-View Neural Radiance Fields
Juntang Wang, Yihan Wang, Sheng'en Li +3
Neural Radiance Fields (NeRF) synthesize photorealistic novel views from dense image collections, but degrade sharply when few views are available. We attribute a specific, measura…
StageGuard: Physiologically Constrained Sleep Staging
Juntang Wang, Yihan Wang, Hao Wu +3
Automated sleep staging is increasingly used in large-scale studies to derive sleep-architecture endpoints: total sleep time, REM latency, sleep efficiency, and bout-duration stati…
Mixing Configurations for Downstream Prediction
Juntang Wang, Hao Wu, Yihan Wang +2
Clustering-based features are widely used in machine learning, but most methods must choose a resolution -- a choice that is global, fixed, and ad hoc. Recent work shows that varyi…
Brain-Inspired Perspective on Configurations: Unsupervised Similarity and Early Cognition
Juntang Wang, Yihan Wang, Hao Wu +2
Infants discover categories, detect novelty, and adapt to new contexts without supervision-a challenge for current machine learning. We present a brain-inspired perspective on conf…
