Artificial intelligence estimates peoples' ages


"We're not quite sure what features our algorithm is looking for," says Professor Laurenz Wiskott from the Institute for Neural Computation. This is because the system has learned to assess faces. The successful algorithm developed by the Bochum-based researchers is a hierarchical neural network with eleven levels. As input data, the researchers fed it with several thousand photos of faces of different ages. The age was known in each case.

Sheep can recognise familiar and unfamiliar faces

You might think sheep only have a woolly sense of what humans look like. But now a study has found that after training, sheep could pick out the faces of four human celebrities presented next to faces they had not seen before. You might think sheep only have a woolly sense of what humans look like. Researchers trained eight sheep to recognise the front-on-faces of four celebrities from photographs. They attempted to find out whether sheep could recognise the four celebrity faces when presented in different perspectives – an ability only previously studied in humans.

Babies use contextual clues to find things of interest

Babies have the capacity to learn, remember and use contextual cues in a scene to find things of interest, such as faces, when they are just six months old, researchers have found. Researchers admit they were shocked by the discovery, and said it could help stop signs of developmental issues such as autism far earlier. 'It was pretty surprising to find that 6-month-olds were capable of this memory-guided attention,' said Kristen Tummeltshammer of Brown, who led the study. 'We didn't expect them to be so successful so young.' In the experiment, which is published in Developmental Science, babies showed a steady improvement in finding faces in repeated scenes, but didn't get any quicker or more accurate in finding faces in new scenes.

Being smarter means you are more likely to use stereotypes

People with higher cognitive abilities are often better able to spot patterns in the world around them, allowing them to excel in a wide range of tasks, from learning languages to recognizing faces. But, in some situations, even being intelligent has its drawbacks. A new study has found that these people are more likely to stereotype others based on the patterns they detect, potentially leading to negative consequences as they perpetuate social biases. A new study found that people with higher cognitive abilities are more likely to stereotype others. In the study, the researchers manipulated image-description pairings so that the faces with particular features were linked to negative stereotypes.
