Latest Patents

One of Guang-Ho Cha's latest patents is an "Indexing system and method for nearest neighbor searches in high dimensional data spaces." This invention involves approximating vectors representing objects in n-dimensional space by using local polar coordinates on partitioned cells of the data space. When a query is made, such as a request to find 'k' nearest neighbors to a query vector, a set of candidate near neighbors is generated using these approximations. The local polar coordinates are independent of the dimensionality of the data space, allowing for efficient processing. The invention acts as a filter to reduce the number of actual data vectors that must be considered in responding to the query, thereby enhancing the speed and efficiency of data retrieval.
