Most of the knowledge in the world in the future is going to be extracted by machines and will reside in machines. – Yann Le. Cun, Director of AI Research, Facebook
Traditional Programming Data Algorithm Computer Output Computer Algorithm Machine Learning Data Output
So How Do Machines Learn? 1. Fill in gaps in existing knowledge 2. Emulate the brain 3. Simulate evolution 4. Systematically reduce uncertainty 5. Notice similarities between old and new
