Bio-inspired Robustness: A Review. (arXiv:2103.09265v1 [cs.CV])

Deep convolutional neural networks (DCNNs) have revolutionized computer
vision and are often advocated as good models of the human visual system.
However, there are currently many shortcomings of DCNNs, which preclude them as
a model of human vision. For example, in the case of adversarial attacks, where
adding small amounts of noise to an image, including an object, can lead to
strong misclassification of that object. But for humans, the noise is often
invisible. If vulnerability to adversarial noise cannot be fixed, DCNNs cannot
be taken as serious models of human vision. Many studies have tried to add
features of the human visual system to DCNNs to make them robust against
adversarial attacks. However, it is not fully clear whether human vision
inspired components increase robustness because performance evaluations of
these novel components in DCNNs are often inconclusive. We propose a set of
criteria for proper evaluation and analyze different models according to these
criteria. We finally sketch future efforts to make DCCNs one step closer to the
model of human vision.
