“Sparsification“
18 February 2025
Abstract
This approach to 3D time series data reduction allows for a smaller node counts by 10,000 to 1,000,000 times over voxels. This also allows for multiple pre computed connectivity graphs to be stored to make simulation and analysis of time series data sets much faster. To further reduce workloads spatial partitioning can be used to support variable density. By assessing the change on a region by region basis it is also re-computed only when certain spatial thresholds are reached.
