Abstract:
Dr. Emin Orhan’s research is aimed at understanding the high level computational principles and lower level circuit mechanisms underlying biological intelligence. His recent work uses deep learning to address these fundamental questions. In the first part of his talk, Dr. Orhan will describe his recent efforts to understand the nature of the neural representations underlying short-term memory maintenance in the brain, using task-trained recurrent neural networks (Orhan & Ma, Nature Neuroscience, 20191). Consistent with experimental findings, his results show that these models display a spectrum of maintenance mechanisms ranging from sequential delay activity to more persistent delay activity depending on a variety of task- and circuit-related factors. The complete experimental tractability of these models also aids a detailed understanding of the circuit level mechanisms underlying this spectrum of solutions. In the second part of his talk, Dr. Orhan will discuss how he can use the insights gained from the first part to improve artificial neural networks (Orhan & Pitkow, ICLR, 20202). Specifically, he will show that sequential neural activity can be used as a novel, useful inductive bias to improve memory in recurrent neural networks solving practical machine learning tasks. Together these two projects illustrate how deep learning and neuroscience can mutually inform each other, to the benefit of both fields.
