Machine Learning for Middle Schoolers--Stephen Wolfram Blog

#artificialintelligence

So the question now is: can one teach the core concepts of modern machine learning even to middle schoolers? The first thing I discuss is something that doesn't really need all the fanciness of modern neural-net machine learning: it's recognizing what languages text fragments are from: Kids (and other people) can sort of imagine (or discuss in a classroom) how something like this might work--looking words up in dictionaries, etc. Suffice it to say that after discussing explicitly trained functions like TextRecognize and ImageIdentify, I start discussing "unsupervised learning", and things like clustering in feature space. Wolfram Notebook system that lets us put all these pieces together--all these pieces are critical to making it possible to bring modern machine learning to people like middle schoolers.


How NASA's Astrobee Robot Is Bringing Useful Autonomy to the ISS

IEEE Spectrum Robotics Channel

Called SPHERES (Synchronized Position Hold Engage and Reorient Experimental Satellites), these robots have spent about 600 hours participating in an enormous variety of experiments, including autonomous formation flying, navigation and mapping, and running programs written by middle school students in team competitions. But beyond serving as a scientific platform, SPHERES weren't designed to do anything especially practical in terms of assisting the astronauts or flight controllers, and it's time for a new generation of robotic free fliers that's fancier, more versatile, and will be a big help for the humans on the ISS. From the beginning, Astrobee was intended to be much more than a successor to SPHERES: It's a completely new platform, designed from scratch to operate autonomously and safely on board the ISS. Astrobee's computing system has three layers of processors inside: one low level, one mid level, and one high level.


How your DNA influences your sex life

Los Angeles Times

A new study of Los Angeles middle school students finds that those who sent or received sext messages were significantly more likely than their non-sexting peers to be sexually active. New research has found that women are on average no more likely to have multiple sexual partners in a single month after they are provided no-cost access to birth control methods than they were before. And while women reported a slight uptick in their reported monthly sexual encounters a year after...
