Researchers have developed a new sampling framework called ACES (Adaptive Coverage-aware Efficient Sampling) to improve the training efficiency of implicit neural representations (INRs). This method decouples domain coverage from importance weighting, using adaptive spatial partitions to ensure comprehensive coverage and reduce redundant sampling. By prioritizing informative regions at a region level, ACES aims to decrease gradient variance and enhance optimization efficiency compared to uniform or pointwise adaptive sampling methods. Experiments show ACES converges faster and achieves lower error, particularly on complex scientific field learning tasks. AI
