Incremental Generation of Differentially-Private Datasets
Incremental Generation of Differentially-Private Datasets

We explore 5 ways of generating data on yellow cabs that differentially-privatizes the original dataset. Methods build upon previous methods until we result in a stable dataset-generating algorithm.

Patient Safety: Adverse effects of antihypertensive drugs
Patient Safety: Adverse effects of antihypertensive drugs

We analyzed trends in adverse effects of antihypertensive drugs and built a model to predict which adverse effect patients are most likely to experience. Our model has a 50% accurancy rate.
