Data Science
This rubric covers the use of statistical tools working on large datasets to create models and derive inferences, as well as coverage of the field in its entirety. This differs from machine learning primarily in that the latter focuses on functional gradient analysis or neural networks (kernels) to derive models.
Simulating COVID-19 with Agent-Based Modeling
Here are some (very) early outputs from an Agent-Based Model of COVID-19 that I’m currently developing. It allows configuring a number of parameters including: population… Read More »Simulating COVID-19 with Agent-Based Modeling
