New method peeks inside the ‘black box’ of artificial intelligence

Computer scientists have developed a promising new approach for interpreting machine learning algorithms. Unlike previous efforts, which typically sought to ‘break’ the algorithms by removing key words from inputs to yield the wrong answer, the researchers instead reduced the inputs to the bare minimum required to yield the correct answer. On average, the researchers got the correct answer with an input of less than three words.

Gut bacteria may control movement

A new study puts a fresh spin on what it means to ‘go with your gut.’ The findings suggest that gut bacteria may control movement in fruit flies and identify the neurons involved in this response.
