MIT researchers have unveiled a "periodic table of machine learning," a groundbreaking framework that organizes over 20 common machine-learning algorithms based on a unifying algorithm. This innovative approach allows scientists to combine elements from different methods, potentially leading to improved algorithms or the creation of entirely new ones. The researchers believe this framework will significantly fuel further AI discovery and innovation by providing a structured approach to understanding and developing machine learning techniques.

The core concept behind this "periodic table" is that all these algorithms, while seemingly different, learn a specific kind of relationship between data points. Although the way each algorithm accomplishes this may vary, the fundamental mathematics underlying each approach remains consistent. By identifying a unifying equation, the researchers were able to reframe popular methods and arrange them into a table, categorizing each based on the relationships it learns. Shaden Alshammari, an MIT graduate student and lead author of the related paper, emphasizes that this is not just a metaphor, but a structured system for exploring machine learning.

Just like the periodic table of chemical elements, this new framework contains empty spaces, representing algorithms that should exist but haven't been discovered yet. These spaces act as predictions, guiding researchers toward unexplored areas within machine learning. To illustrate the framework's potential, the researchers combined elements from two different algorithms, resulting in a new image-classification algorithm that outperformed current state-of-the-art approaches by 8 percent. The researchers hope that this "periodic table" will serve as a toolkit, allowing researchers to design new algorithms without needing to rediscover ideas from prior approaches.

NASA astronaut Chris Williams, who earned a doctorate in physics from MIT in 2012, is set to launch to the International Space Station (ISS) on a Russian Soyuz rocket no earlier than November 2025. The rookie astronaut, a member of NASA's 23rd astronaut class, will join cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev aboard the Soyuz MS-28, launching from Baikonur Cosmodrome in Kazakhstan. Williams will spend approximately eight months on the ISS as part of Expedition 74, serving as a flight engineer and continuing ongoing microgravity investigations into the effects of spaceflight.

This mission marks Williams' first assignment to space after completing his training. Prior to joining NASA, Williams completed a Medical Physics Residency training at Harvard Medical School and conducted research as a clinical physicist at Brigham and Women’s Hospital. His selection for the Soyuz MS-28 mission follows the recent launch of fellow classmate Nichole Ayers on SpaceX's Crew-10 mission and the selection of Andre Douglas as part of NASA's Artemis 2 backup crew. The MS-28 crew will replace the MS-27 astronauts, including NASA's Jonny Kim, who arrived at the ISS in April.

Separately, a new physics model has been developed to analyze the intricacies of bowling and determine the optimal conditions for achieving strikes. The model utilizes six differential equations relating to a rotating rigid body. This research considers several factors that influence a bowling ball's trajectory, including the composition and application of oil on bowling lanes, as well as the inherent asymmetries of bowling balls. The team of physicists involved in the study includes individuals with a strong background in bowling, including one who serves as a coach for Team England at the European Youth Championships. The study aims to move beyond statistical analysis of empirical data and provide a more comprehensive understanding of the physics behind bowling.
