Despite recent progress in artificial intelligence, humans and animals still vastly surpass machine observers in their ability to reason about their environment. In particular, biological systems generalize to new concepts much more efficiently, flexibly, and robustly than their artificial counterparts. What is it about biological perception that supports these fundamental qualities?

My research aims at addressing this question by investigating distinctive properties of biological vision, and building artificial systems that capture them. Specifically, by understanding how neural representations of the environment are structured, we can assess whether current artificial systems are similarly organized, and if not, incorporate this structure into their learning paradigm.

For example, we found that human perceptual representations were structured to facilitate the prediction of natural videos, a property lacking from current artificial recognition systems. In turn, enforcing artificial representations to be more predictable enabled them to learn about new image classes much more efficiently.
