I read a very interesting recent paper from Jim Dicarlo’s lab at MIT that gives another strong piece of experimental evidence for temporal slowness based learning of invariant representations. The paper, authored by Nuo Li and DiCarlo found that size tolerance in the visual cortex can be altered by changing the temporal statistics of the visual world. Compared to their earlier studies that showed the same thing for position tolerance, the new study shows that size tolerance reshaping can be induced under naturally occurring dynamic visual experience, even without eye movements.
If we live in a world where whenever we see a cat we see a dog right after, we will say that cats and dogs are the same things! I am sure that Nuo’s and Jim’s experiments have left a lot of monkeys similarly confused.
