Course Description

The real world is messy and your job is to make sense of it. Toy datasets like MTCars and Iris are the result of careful curation and cleaning, even so the data needs to be transformed for it to be useful for powerful machine learning algorithms to extract meaning, forecast, classify or cluster. This course will cover the gritty details that data scientists are spending 70-80% of their time on; data wrangling and feature engineering. With size of datasets now becoming ever larger, let's use PySpark to cut this Big Data problem down to size!

    Feature Engineering

    In this chapter learn how to create new features for your machine learning model to learn from. We'll look at generating them by combining fields, extracting values from messy columns or encoding them for better results.

I have a strong drive for innovation and giving back. Through my work I enjoy building out a career path and center of excellence for those in data science at General Mills. I have a passion for taking action and challenging the status quo with fact based analysis to drive results. Outside of work I enjoy running an organization that gives aspiring and practicing data scientists opportunities to show case their skills in a meaningful way.
