[Science daily] Breaking AIs to make them better
Current AIs are very accurate but inflexible at image recognition. Exactly why this is remains a mystery. Researchers have developed a method called 'Raw Zero-Shot' to assess how neural networks handle elements unknown to them. The results have the potential to help researchers identify (...)
[Science daily] Capturing an elusive shadow: State-by-state gun ownership
In a new study, researchers describe a spatio-temporal model to predict trends in firearm prevalence on a state-by-state level by fusing data from two available proxies -- background checks per capita and suicides committed with a firearm in a given state. Calibrating their results with yearly (...)
[Science daily] Artificial intelligence techniques used to obtain antibiotic resistance patterns
New research analyzes antibiotic resistance patterns, with the aim of finding trends that can help decide which treatment to apply to each type of patient and stop the spread of bacteria.
[Science daily] Tracking a levitated nanoparticle with a mirror
Sensing with levitated nanoparticles has so far been limited by the precision of position measurements. Now, researchers have demonstrated a new method for optical interferometry in which light scattered by a particle is reflected by a mirror. This opens up new possibilities for using levitated (...)
