Academic Projects Multimedia Data Indexing and Retrieval Fall 2014 • Developed an efficient indexing and retrieval data scheme for a spatio-‐temporal, time-‐series data. The dataset working on an epidemic simulation datasets across all the states of USA over a period of seven months. • Reduced the number of features of the high-‐dimensional dataset using Latent Semantic analysis by performing techniques like SVD and LDA. • Optimized the search time by implementing indexing tools like VA-‐filters and Locality Sensitive Hashing. Reduced the search time by upto 80 percent due by using the above indexing tools. Used Matlab for the entire project. Geometric Operations on Geospatial Data Spring 2015 • Performed spatial join and range queries, polygon union and extracted convex hull of large data consisting of polygons • Set up a distributed system of nodes to divide the work among master and slaves and implemented map reduce paradigm. Accessed and stored data using HDFS. • Setup cluster using Hadoop 2.6.0 and Spark 1.2.0. Reduced response time by 80% when setup a cluster of five nodes as compared to single node system. Online Banking Application Spring 2014 • Developed an online banking application using a Service Oriented Architecture Software Design. • Developed individual services like handling accounts, mobile notifications, finding nearest banking locations, etc. • Developed in C# using .NET framework including XML, JSON parsing, Session states, Google API. Chicken Farm application (Distributed Service Development, Service Oriented Architecture) Spring 2014 • Developed a service that allows a number of retailers to place orders and the chicken farm processes these applications in an orderly fashion. • The orders are placed by a synchronized access to a global data structure that contains orders. These orders are encrypted and sent over to the chicken farm where it is decrypted before processing the order. • Used C# on a .NET framework to develop this service. Based on SOA. Twitter Sentiment Analysis (https://github.com/viswanth/Twitter-‐Sentiment-‐Analysis) Summer 2014 • Extract real time tweets from Twitter and analyse the sentiments of the tweet. • Used to predict the trending tweets on Twitter and also to analyse the mood of the people in a particular geographical region based on their tweets. • Used Python to work with the Twitter API and extract information out of the JSON provided by Twitter
- 2. Tidy Dataset (https://github.com/viswanth/TidyData) Summer 2014 • The purpose of this project is to collect, work with, and clean a raw dataset. • The raw dataset worked upon here is a multivariate time-‐series built from the recordings of 30 subjects performing daily life activities while carrying waist-‐mounted smart phone. • Extracting the useful information, summarising the data in a clean independent tidy data that is created. Custom Kernel Module for Communication Fall 2014 • Downloaded and compiled the Linux Kernel source code so I can add my custom module to the Kernel. • My custom module will communicate with other modules created by other students in the class. Full duplex communication via iPv4 achieved by replacing the standard socket interface used by most network programs. • Implemented logical clock in the module to have a time ordering of the messages. Entire class used the same protocol number to allow communication with each other. Q2A++ Fall 2013 • Developed an online learning community to enhance the learning experience of users. • Fixed Presented new features in Question and Answer Communities like Profile based tags, Homogeneous and Heterogeneous Group Suggestions. • Using PHP, HTML, CSS, Apache Tomcat and MySQL.
