Unboxing Data Science (Short Verison)

Unboxing Data Science (Short Verison)

If you believe data can power and disrupt businesses this talk is for you. In this talk you will join me into an overall unboxing of data science, how I learned and used it to empower a company I worked with, enabling them to take conscious and informed decisions on how to react and plan ahead on different circumstances. A great chance to learn data science and how to apply it in real life.
