A message from DSI’s new Director of Technology Policy, Nick Feamster

Figures 1a-b show the general strategy: during a training period (fig. 1a), a time-dependent state is imposed on the system. This is pictured by an origami bird whose wings are periodically moved by an external agent. After training (fig. 1b), a retrieval period during which the physical system evolves under the learned dynamics should lead to a dynamic state that matches the training as best as possible. (fig. 1c and 1d) Demonstration of the training and retrieval procedure using a programmable LEGO toy. The angular positions of two motors are imposed by hand during a training phase (fig. 1c), during which couplings between the motors are learned. Dynamics during retrieval, with learned couplings, can produce fixed points as well as dynamic states where the angles constantly change (fig. 1d). See this video for a detailed description.

AI as a Great Teacher for Molecular Dynamic Modeling

AI methods and models have enabled a huge leap in our understanding of how images are processed in the brain.
We used to describe visual neurons as “edge detectors” and “face detectors”. Using deep neural networks, we have
discovered that images like these (which really can’t be described with words) are richer models of single neurons in
our visual system. I liken these AI-enabled descriptions of neural function, perhaps ironically, to a whole new kind of
vocabulary that neuroscientists can now use to explain the visual system. (Images from various papers including a,b, c, d, e , f)
