How machine learning systems sometimes surprise us

By | cognitive science, energy, Gadgets, learning, machine learning, neuroscience, simulation, spreadsheet, TC

This simple spreadsheet of machine learning foibles may not look like much but it’s a fascinating exploration of how machines “think.” The list, compiled by researcher Victoria Krakovna, describes various situations in which robots followed the spirit and the letter of the law at the same time. For example, in the video below a machine […]

Auxetics are materials that store energy internally rather than bulging out. In this way they can store more energy when squeezed or struck and disperse it more regularly. Historically, however, these materials have had sharp corners that could break easily with enough pressure. Now researchers at Queen Mary University of London and University of Cambridge […]

New technique brings secrets out of old daguerreotypes

By | energy, Gadgets, TC, X Ray

Daguerreotypes – photos made with a process that used mercury vapors on an iodine-sensitized silvered plate – break down quite easily. The result is a fogged plate that, more often that not, is completely ruined by time and mistreatment. However, researchers at Western University have created a system that uses synchrotrons and “rapid-scanning micro-X-ray fluorescence […]
