Title:                “Data Science Application in Financial Sectors”

Abstract:          This presentation provides an overview of the different data analytics applications in the industry, with a focus on the Property and Casualty Insurance industry. A case study based on the most recent Liberty Mutual Kaggle Competition will be discussed in more details. The presenter will share the #1 winning team's insights to address this difficult problem. Keys to their success include capping, downsampling, feature selection and a bit of feature engineering to extract value and remove noise from blocks of features. The winners also explored diverse combinations of feature transformations and ML algorithms. An ensemble of RandomForest, ExtraTrees and Linear models generated by DataRobot proved to be the lucky winner!
