Title: G D Ramkumar: Innovator in Data Classification and Mining
Introduction
G D Ramkumar is a notable inventor based in Mountain View, CA (US). He has made significant contributions to the field of data classification and mining, holding a total of 3 patents. His work focuses on enhancing the accuracy and efficiency of data processing techniques.
Latest Patents
One of his latest patents is titled "Method and apparatus for classification of high dimensional data." This invention presents an apparatus and method for classifying high-dimensional sparse datasets. The process involves flattening a raw data training set by converting it from categorical representation to a boolean representation. This flattened data is then utilized to build a class model, allowing for the classification of new data not included in the training set. In one embodiment, the class model takes the form of a decision tree, using large itemsets and cluster information as attributes for classification. Another embodiment is based on the nearest neighbors of the data to be classified. The advantages of this invention include increased classification accuracy by eliminating artificial ordering induced on the attributes and the enhancement of accuracy through the use of large itemsets and clustering.
Another significant patent by G D Ramkumar is "Method and apparatus for dynamically counting large itemsets." This invention is directed towards a data mining method and apparatus that dynamically initiates the counting of itemsets at any time during the pass over the records of a database. It terminates the counting at the same location in the next pass, allowing for early counting and completion while maintaining a relatively low number of different itemsets being counted in any pass.
