Marketing Predictive Analysis in SAS August 2018 - December 2018

• Collaborated on SAS Enterprise Miner to predict Optimal housing prices in residential homes at Ames, IOWA. Conducted cluster analysis and segmented customers based on their behavior, implemented various predictive models like logistic, linear, neural networks to identify impact on demographics on house prices.

• Compared predictive models using SAS model comparison node, Fit Statistics results to estimate that Linear regression is a better model for price estimation.

Data Modeling using Python and Visualization using Tableau

• Cleansed Kaggle TITANIC dataset, performed data pre-processing and EDA in python using various packages like seaborn, NumPy, Pandas and developed predictive models like decision trees, Gradient boosting, Naïve Bayes Classifier and KNN, identified random classifier as good predictor with 95.8 score.

• Performed clustering on the dataset using TabPy and visualized in Tableau based on “Survival by passenger class”, “Age Category”, “Embarked Point”.

Data Visualization Using D3 and Gephi and QlikView

• Visualized University’s Food Sales data using D3 and using hierarchical maps, Used SVG containers to contain tree map and link it via JavaScript, created transition/navigation for navigating to inner child elements as a part of hierarchical map to identify which product is the highest sold for each chain in the University.

• Analyzed large networks using Gephi, focused on relationship between Apple and other websites and with itself, identified which website has the strongest connection with Apple. Ran both Fruchterman Reingold and Yifan Hu for clustering by industry, clustered using Internal or External Linkage running the Yifan Hu Proportional algorithm by using Average Weighted Degree.

• Exercised multi views aka Trellis maps using QlikView to track youth Employment, income and expenditure trends over the years globally to identify new markets for Business, dips in youth employment and expenditure over the years. LEADERSHIP & ORGANIZATIONS
