This document discusses how data science can be used for social good. It provides examples of using data science to predict things like diabetes, detect carcinogens during cancer treatment trials, predict soybean yields to help farmers, and predict optimal times for wind energy to help wind turbines. Additional examples discussed include mapping health services availability across regions to identify gaps, and using predictive maintenance to determine when sensors may wear out based on location and past issues. The document emphasizes that data science can help improve areas of social good like public health, transportation, the environment, and more.
