DATA VISUALIZATION DEVELOPER

Jan 2018

With this project, I helped the IRRIS department by developing Tableau visualizations that answer strategic business questions posed forth by key decision makers of the University . I created interactive dashboards using live data fetched from the data warehouse that helped identify key trends and gather relevant insights from the historical data.

ACADEMIC PROJECTS

While pursuing my Master's degree in Information Sciences, I have had the chance to work on different academic projecs focussing on data analytics. Through the projects done as part of the course curriculum, I also gained an opportunity to learn and work with different statistical tools such as R, Python, SAS and Stata in addition to applying the knowledge imparted by the course.

BRAND ANALYSIS ON LUXURY SEDANS

Technologies used: Python Scripting, Gephi, Microsoft Excel


In this project, I got to analyze on unstructured data scraped from popular car discussion forums. Lift Analysis was performed to reveal clusters of brand association, which was visualized using a Multi Dimensional Scaling plot. Relevant attributes associated with each brand were identified and the lift scores calculated to measure the magnitude of association. I also perfromed a sentiment Analysis on the posts, based on which I created a bi-directional Product Comparison network. Page Rank score was calculated based on the network to observe a correlation between the scores and the sales figure.

SOCCER RESULT PREDICTOR

Technologies used: R, Machine Learning Algorithms

The English premiere league data for the 2014/2015 season was analyzed using R. The goal being to identify certain predictors that most strongly affect the probability of winning a match and construct a model based on the most predictive variables. To reduce the dimensionality of the predictor set, PCA was applied. Different models and machine learning algorithms (Random Forest, K‐Nearest Neighbor, and Multinomial Logit regression, Linear Discriminant Analysis, Quadratic Discriminant Analysis) were applied and a maximum accuracy of 68% was obtained.

ONLINE ADVERTISING CTR PREDICTION

Technologies Used: R, Weka, Machine Learning Algorithms, Model Evaluation Technique

Worked on dataset obtained from a kaggle competition hosted by Avazu to predict the click through rate (CTR) of a customer given certain predictor variables. I carried out exploratory analysis to determine the relevant predictors, and applied various machine learning algorithms to the data. Different model evaluation techniques were implemented to evaluate the performance of the various model.

ANALYSIS OF UN VOTING PATTERNS

Technologies used: R, Gephi, Node XL, Microsoft Excel

The UN votes from the year 1946-2015 was collected from kaggle.com to study the voting behavior of different countries across different issues and timelines. Different metrics like betweenness, centrality was used to gain more insights into the voting cluster behavior of the countries. Gephi was used to visulize this behavior.

MOVIE SUCCESS PREDICTOR

Technologies used: Microsoft Excel, Python, SQL, Web Scraper

This project involved wrangling data from multiple sites. Using python, the data was cleaned and stored in the database server. SQL queries were run to get the required data to analyze the relationship between the movie’s success and various predictors. A multi‐variable regression model was applied. Visualizations in the form of graphs were plotted using Excel.
