PROJECTS

Indiana University, Bloomington Jan 2016–Aug 2017

• Modeled Worker’s compensation problem using random forest, with dataset having over 3 million instances.

• Implemented a depression analyzer with Naïve Bayes algorithm using DAIC-WOZ data-set to analyze if the interviewee had depression based on answers to questions, using DAIC-WOZ as training data-set and data from reddit r/depression and r/sucidewatch as test dataset.

• Implemented Automatic Image Colorization by example, where a gray scale image is colored using a reference image.

• Implemented a Radial Basis function model with kernel representation for feature transformation. Trained models on UCI SUSY dataset and compared accuracies of the models.

• Implemented binary classifiers (Naïve Bayes, Decision trees, Random forest, KNN, SVM, Logistic Regression, Ada Boost) on UCI adult census data-set and Wisconsin breast-cancer dataset using scikit-learn compared the classifiers performance.
