The Mathematics of Machine Learning
Wale Akinfaderin, a research scientist intern at IBM Research, has written an article on the mathematical background required to fully understand machine learning. He includes a list of educational resources for those who wish to brush up in certain areas. Wale correctly stresses that you don't need this level of knowledge to start making use of machine learning. There are many packaged … [Read more...]
First death in a self-driving car
The first death in a self-driving car occurred in May 2016. It was in a Tesla Model S travelling along a Florida highway. Apparently the car's Autopilot system got confused by a white truck against a bright sky and failed to brake. When AI systems fail, they sometimes fail big. Tesla noted in a press release this is the first fatality in 130 million miles, compared to an average of one fatality … [Read more...]
