  • Depatment of Computer Science and Engineering IIT Delhi
    Machine Learning Research Intern
    Depatment of Computer Science and Engineering IIT Delhi
    May 2012 - Jul 2012 (3 months)
    The tool we developed was an SVM Solver which had options to choose among the various feature selection methods to solve problems with large scale data. An independent Localized Linear SVM solver was also implemented that used clustering as a pre-processing step. The program was later expanded to have multiple kernel options, and then an approximation of the RBF kernel was added, using Random Fourier Features. Final results were reported in terms of classification accuracy and training time. Project Guide - Prof. K. K. Biswas
