Presented at the PyData Cardiff meetup, Cardiff, April 2018.
Once confined to the corridors of academia, data science and machine learning are now having a massive impact on the world of business and beyond. There have been significant technological advances in just the last 10 years alone, from the explosion of open source software to the big data revolution, to yield what The Economist now calls the fourth industrial revolution.
In this talk we'll go beyond the hype and understand what data science really is, where it came from and where it's going. We'll demystify the field of machine learning, explain the terminology and see examples of how popular techniques are being used in practice. Finally, we'll see how you can get started by exploring the PyData ecosystem and provide concrete next steps towards a career in what the Harvard Business Review has dubbed "the sexiest job of the 21st century".
