Latest Patents

One of Junhyeok Jang's latest patents is a "Method and apparatus for accelerating GNN pre-processing." This invention provides an apparatus designed to enhance the efficiency of graph neural network (GNN) pre-processing. 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 and conducts uniform random sampling on selected nodes of a given node array. Additionally, it 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 organizes the edges into CSR format.

Another notable patent is a "Data storage device for determining a write address using a neural network." This device comprises one or more nonvolatile memory devices, each containing multiple unit storage spaces. The address recommending circuit within the device is designed to suggest a unit storage space for processing write requests. It utilizes feature data applied to a neural network to recommend the appropriate storage space, with the feature data generated based on request information, target addresses, and existing data addresses.
