Efficient Parallel and PEM Algorithm for Geometric Query Problem using Segment Trees, Studies the computation, communication, and synchronization requirements related to the construction and search of parallel segment trees in an architecture-independent way., Designed parallel and parallel external memory algorithms are optimal in space and time compared to the corresponding existing sequential algorithms. Political Alliance Prediction, Developed a system that can detect the pattern exhibited by the politicians and predict the alliance formation between politician to party with 90.54% accuracy on Twitter data of Indian politicians., Gephi is used to visualize complex and dense mention and retweet network. Politician embedding generation, classification, deep walk, and CNN are used to further predict party to party alliance formation. Speech based Vowel Recognition System, Developed an application that can predict the vowel based on its phonetic sound using live and pre-recorded voice notes., Achieved 90% accuracy for live recordings and 95% accuracy for pre-recorded voice notes., Linear predictive coding is used to generate cepstral coefficients, LBG algorithm is used to make a codebook, Tokhura distance is used to find the closest vowel.
