Latest Patents

Hyunkyu Choi holds a patent for a "Method and apparatus for accelerating GNN pre-processing." This invention provides an apparatus designed to accelerate the pre-processing of graphs. The apparatus includes a set-partitioning accelerator that sorts each edge of an original graph stored in a coordinate list (COO) format by node number. It performs radix sorting based on vertex identification (VID) to generate a COO array of a preset length. Additionally, it conducts uniform random sampling on selected nodes of a given node array. The invention also features a merger that combines the COO array into a single sorted COO array, a re-indexer that assigns new consecutive VIDs to the sampled nodes, and a compressed sparse row (CSR) converter that transforms the sorted edges into CSR format.
