Building explainability into the components of machine-learning models

Posted: 30 Jun 2022 10:48 AM PDT

Researchers have created a taxonomy and outlined steps that developers can take to design features in machine-learning models that are easier for decision-makers to understand.

Breaking AIs to make them better

Posted: 30 Jun 2022 08:45 AM PDT

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 the common features that make neural networks 'non-robust,' and develop methods to make AIs more reliable.

Common gene used to profile microbial communities

Computer scientists develop Emu, an algorithm that uses long reads of genomes to identify the species of bacteria in a community. The program could simplify sorting harmful from helpful bacteria in microbiomes like those in the gut or in agriculture and the environment.

Making dark semiconductors shine

Posted: 27 Jun 2022 09:49 AM PDT

The energy-levels of semiconductors can be rearranged by coupling between light particles (photons) and excited electrons so that a formerly dark material becomes optically active. In their experiments, the researchers succeeded in manipulating the energy-level structure in an ultra-thin sample of the semiconductor tungsten diselenide. This material, which normally has a low luminescence yield, began to shine, the team reports.
