  • Usage Based Insurance based on Clustering and Machine Learning techniques

          UBI is ‘pay how you drive (PHYD)’, a type of vehicle insurance whereby the cost is dependent upon type of vehicle

          used, driving time, distance, behavior and place. Main goal of this project is to provide rare event (Harsh Accelera-

          tion and Harsh Breaking as a dangerous behavior) detection method through machine learning techniques with

          the massive data from the connected vehicles. Extracting behavioral driving patterns and defining the behavioral

          patterns in various perspectives with clustering.

 

 

PROJECTS

Implementation of Distributed Key-Value Store System                                                          Apr 2018 – May 2018

Proposed new design of distributed key-value store.Building hierarchical layered consistent hash ring based distributed

key-value store Library

Gesture Detection & Classification                                                                                                    Mar 2018 – May 2018

Main goal of this project was to extract and analyze human behavior through the video data. Creating new feature that

is not linearly corelated to other features and reinforces the characteristics of time series data through KDD(knowledge

discovery in database) 

Implementation of Recoverable Virtual Memory Library                                                         Mar 2018 – Apr 2018

Building Recoverable Virtual Memory Library, which is software defined persistent virtual memory in the face of system crash.

Develop Inter-Process-Communication Service                                                                            Feb 2018 – Mar 2018

Building XEN style Inter-Process Communication Services Library for Domain and Clients VMs. Implementing Hypervi-

sor, Domain and Clients to test the library.

Implementation of Credit Scheduler                                                                                                   Jan 2018 – Jan 2018

Building Credit-based Thread Scheduler, which is proportional fair-share mechanism based on weight and cap.

Multi-modal Music Classification using Deep Learning                                                                 Sep 2017- Dec 2017

Main goal was to provide multi-modal classification system for music’s genre, years and gender of artist based on various

type of source(audio, lyrics and album covers). Let alone audio data which has the richest information, lyrics and album

covers are also good source of information at classifying gender of artist. Ensemble of three classification systems reinfor-

ces the final result.

Implementation and Evaluation of Deep Learning                                                                         Sep 2017 – Oct 2017

Evaluation of hyperparameters in Image Classifier using Convolutional Neural Network. Understanding the role of

hyperparameters that affects the overall performance of ML and address how to tune hyperparameters.
