Someone learning to play tennis might hire a teacher to help them learn faster. Because this teacher is (hopefully) a great tennis player, there are times when trying to exactly mimic the teacher won’t help the student learn. Perhaps the teacher leaps high into the air to deftly return a volley. The student, unable to copy that, might instead try a few other moves on her own until she has mastered the skills she needs to return volleys. Computer……

When machine-learning models are deployed in real-world situations, perhaps to flag potential disease in X-rays for a radiologist to review, human users need to know when to trust the model’s predictions. But machine-learning models are so large and complex that even the scientists who design them don’t understand exactly how the models make predictions. So, they create techniques known as saliency methods that seek to explain model behavior. With new methods being released all the time, researchers from MIT……

In October 2020, two rival candidates for office in Utah made an unusual television ad together. Incumbent Republican Gov.

Such reassurances are unusual, however, and can be overwhelmed by other messages. Indeed,……

More than 5,000 planets are confirmed to exist beyond our solar system. Over half were discovered by NASA’s Kepler Space Telescope, a resilient observatory that far outlasted its original planned mission. Over nine and a half years, the spacecraft trailed the Earth, scanning the skies for periodic dips in starlight that could signal the presence of a planet crossing in front of its star. In its last days, the telescope kept recording the brightness of stars as it was……

In the mid-1980s, artist Pamela Z was working at Tower Records on Columbus Street in San Francisco, where one of her jobs was replacing pages in the store’s Phonolog, an enormous alphabetized directory of all the music available at the time, which formed a kind of bible of pop. When she ripped one loose-leafed sheet from the book, she noticed that all the titles on that sheet began with “you.” You stayed on my mind. You stole my heart…….
