Memory Defense: More Robust Classification via a Memory-Masking Autoencoder

Kavli Affiliate: Dan Luo | First 5 Authors: Eashan Adhikarla, Dan Luo, Brian D. Davison, , | Summary: Many deep neural networks are susceptible to minute perturbations of images that have been carefully crafted to cause misclassification. Ideally, a robust classifier would be immune to small variations in input images, and a number of defensive […]

Deep sub-wavelength localization of light and sound in dielectric resonators

Kavli Affiliate: Mohammad Mirhosseini | First 5 Authors: Alkim Bozkurt, Chaitali Joshi, Mohammad Mirhosseini, , | Summary: Optomechanical crystals provide coupling between phonons and photons by confining them to commensurate wavelength-scale dimensions. We present a new concept for designing optomechanical crystals capable of achieving unprecedented coupling rates by confining optical and mechanical waves to deep […]

Active entanglement enables stochastic, topological grasping

Kavli Affiliate: Robert Wood | First 5 Authors: Kaitlyn Becker, Clark Teeple, Nicholas Charles, Yeonsu Jung, Daniel Baum | Summary: Grasping, in both biological and engineered mechanisms, can be highly sensitive to the gripper and object morphology, as well as perception, and motion planning. Here we circumvent the need for feedback or precise planning by […]
