With the abundance of well-documented machine learning (ML) libraries, it’s fairly straightforward for a programmer to “do” ML, without any understanding of how things are working. And we encourage this “black boxes” machine learning! (At least to start.) However, to make proper use of these ML libraries, one needs to be conversant in the basic vocabulary, concepts, and workflows that underlie ML. We’ll introduce the standard ML problem types (classification and regression) and discuss prediction functions, feature extraction, learning algorithms, performance evalution, cross-validation, sample bias, nonstationarity, overfitting, and hyperparameter tuning. This lecture may be safely skipped by those already familiar with practical machine learning. Access the full course at https://bloom.bg/2ui2T4q
#shorts Last year, Detroit police arrested Robert Williams on his front lawn in front of his wife and children. His alleged crime? Face recognition technology had matched his photo from an old driver’s license to an image taken from blurry surveillance footage of a local shoplifting incident. Face recognition technology has been shown time and time again to be biased against people of color and other marginalized groups, who are misidentified at higher rates. When police showed Robert the surveillance image, he said, “I hope you all don’t think all Black people look alike.” #shorts
MIT Cosmologist Max Tegmark explains that gravity “slows down” time. Max shows that time is relative even out in the cosmos at a monster black hole. Known as “Mad Max” for his unorthodox ideas and passion for adventure, Max Tegmark’s scientific interests range from precision cosmology to the ultimate nature of reality. He is author or coauthor of more than two hundred technical papers, twelve of which have been cited more than five hundred times. He has been featured in dozens of science documentaries, and his work with the SDSS collaboration on galaxy clustering shared the first prize in Science magazine’s “Breakthrough of the Year: 2003.” He holds a Ph.D. from the University of California, Berkeley, and is a physics professor at MIT.

Artificial intelligence is being used to do many things from diagnosing cancer, stopping the deforestation of endangered rainforests, helping farmers in India with crop insurance, it help you find the Fyre Fest Documentary on Netflix (or Hulu), or it can even be used to help you save money on your energy bill. But how could something so helpful be racist? Become an Inevitable/Human: https://inevitablehuman.com/
