Learning Fill-in Reduction Ordering via Graph Policy Optimization for Sparse Matrices

ICASSP 2026poster

Matrix reordering in large sparse solvers seeks a permutation that minimizes factorization fill-in to reduce memory and computation. Because the minimum fill-in ordering problem is NP-complete and fill-in is implicit in the sparsity pattern, graph-theoretic heuristics are used. Existing reinforcemen…

TCATSEG: A TOOTH CENTER-WISE ATTENTION NETWORK FOR 3D DENTAL MODEL SEMANTIC SEGMENTATION

ICASSP 2026poster

Accurate semantic segmentation of 3D dental models is essential for digital dentistry applications such as orthodontics and dental implants. However, due to complex tooth arrangements and similarities in shape among adjacent teeth, existing methods struggle with accurate segmentation, because they o…
