Data Science Programming (Retinal Image Classification of Diabetics to detect need of surgery)

• Analyzed a Kaggle dataset to check the given diabetic people need retinopathy. The dataset consisted of around 4K train and 2K test images.

• Used Python to extract images into arrays, and after sorting applied algorithms like Gaussian NB, SVC and Decision Tree classifier to see which model works better.

• Implemented hyper parameter tuning to acquire best results via SVC Classifier(65%). Data Visualization (HART & Bull Runner usage over the years) CUTR (Center for Urban Transport and Research)

• Performed data visualization of an on-campus survey data and solved important transport queries using Power BI to help the on-campus transport & research organization address transport issues in the university.

• Made use of several powerful Power BI charts like Funnel charts, Donut charts & Bar/Column charts to derive results. Independent Research (Removing Biasness in data using COMPAS algorithm)

• Analyzed an IBM dataset called the COMPAS, which is based on the FAIRML algorithm used to analyze recidivism for different kinds of people.

• Worked on an algorithm named the Disparate Impact remover and used Logistic Regression to model and derive the results.

• Produced an accuracy of 85% odd in successful mitigation of the biasness in the data.

• Made use of python packages like sklearn, matplotlib, numpy and pandas to achieve the same. Data Analytics (Auto insurance)

• Formulated regression models using R to understand how the insurance companies think when providing the customers with lifetime values such as factors like the type of vehicle, its cost, etc.

• Analyzed the models using hypotheses testing using ANOVA, Chi-Square, T-test and drew inferences indicating the best possible model in the lot, to be used for prediction. Used libraries such as ggplot, randomforest, dplyr for analysis.

• Applied machine learning algorithms (OLS, Logit) to the models and provided results with 90% accuracy. Data Visualization (Global Drugs consumption)

• Analyzed an original UN dataset and used it to draw charts in Tableau, to depict the drug workflow in the world.

• Made use of the time-series graph, apart from few others like maps, pie charts, to draw conclusions with the dataset.

• Followed the ETL process of Formatting columns through pandas, reproducing the Excel sheet and pushing into the tableau servers to get the results.
