Data science is about extracting knowledge from data and creating practical, actionable insights to improve some facet of a business
Making sure that data insights are useful to people who don’t think about machine learning all day is super important, since the beneficiary of data science work is often a front-line employee, a customer/user or another non-technical stakeholder. For this reason–at least for us at Yhat–data science and product-building go hand-in-hand. Sure, we’re data junkies and enjoy walking the parameter space as much as the next guy or girl. But the kicker for us in any data analysis project is the "why".
