Sensors Group Research Areas

The Sensors Group develops neuromorphic sensors, network  models, and algorithms aimed at mimicking and understanding the computation underlying biological sensors and brain processing. Much of our research is within the field of neuromorphic engineering, a field that is inspired by the way our brain computes.

Our neuromorphic DVS, DAVIS, and DAS event sensors emulate the operating principles of the biological retina and cochlea. The retina pixels or cochlea channels output activity-driven events that encode features useful for downstream tasks. This asynchronous detection process leads to a compressed, sparse output with low latency and high temporal resolution. Furthermore the retina sensor "event cameras" provide high dynamic range of illumination.

Our neuromorphic digital AI deep neural network accelerators also exploit key notions of sparse brain computing to save energy and time.  Our CNN accelerators NullHop and its descendants exploit activation sparsity and our multiple generations of RNN accelerators DeltaRNN, EdgeDRNN, and SPARTUS exploit temporal sparsity and weight sparsity.
