Real-life examples bring new energy to core thermodynamics course
December 20, 2019
This year, the mechanical and aerospace engineering department's thermodynamics class became a Campus as Lab course, featuring field trips, guest lectures and lessons that enhanced students’ learning with examples of energy technology and policy from the University campus and surroundings.
'Grow-and-prune' AI mimics brain development, slashes energy use
December 19, 2019
In a pair of papers published earlier this year, researchers showed how to start with a simple design for an AI network, grow the network by adding artificial neurons and connections, then prune away unused portions leaving a lean but highly effective final product. Growing and pruning results in software that requires a fraction of the computational power, and so uses far less energy, to make equally good predictions about the world. Constraining energy use is critical in getting this kind of advanced AI — called machine learning — onto small devices like phones and watches.
