Researchers at the Weizmann Institute of Science in Israel have gained new insights on humans' ability to recognize faces using deep neural networks.
The researchers compared brain activity to these networks by analyzing data from 33 epileptics with implanted brain electrodes as they were shown a series of faces, each of which triggered a unique neuronal activation pattern.
The neural network was shown the same images, to determine whether it would exhibit activation patterns similar to the human brain.
There were striking similarities, especially in the network's middle layers, which represent the actual pictorial appearance of the faces.
Weizmann's Shany Grossman said, "These findings can help advance our understanding of how face perception and recognition are encoded in the human brain [and] ... may also help to further improve the performance of neural networks, by tweaking them so as to bring them closer to the observed brain response patterns."
