Fourier Features Let Networks Learn High Frequency Functions in Low Dimensional Domains
Matthew Tancik,Pratul P. Srinivasan,Ben Mildenhall,Sara Fridovich-Keil,Nithin Raghavan,Utkarsh Singhal,Ravi Ramamoorthi,Jonathan T. Barron,Ren Ng +8 more
TL;DR: An approach for selecting problem-specific Fourier features that greatly improves the performance of MLPs for low-dimensional regression tasks relevant to the computer vision and graphics communities is suggested.

Wireless Recording in the Peripheral Nervous System with Ultrasonic Neural Dust
Dongjin Seo,Ryan Neely,Konlin Shen,Utkarsh Singhal,Elad Alon,Jan M. Rabaey,Jose M. Carmena,Jose M. Carmena,Michel M. Maharbiz +8 more
TL;DR: Neural dust is demonstrated, a wireless and scalable ultrasonic backscatter system for powering and communicating with implanted bioelectronics and passive, battery-less communication using backscatter enables high-fidelity transmission of electromyogram (EMG) and electroneurogram (ENG) signals from anesthetized rats.

Fourier Features Let Networks Learn High Frequency Functions in Low Dimensional Domains
Matthew Tancik,Pratul P. Srinivasan,Ben Mildenhall,Sara Fridovich-Keil,Nithin Raghavan,Utkarsh Singhal,Ravi Ramamoorthi,Jonathan T. Barron,Ren Ng +8 more
TL;DR: In this paper, Fourier feature mapping is used to transform the effective neural tangent kernel into a stationary kernel with a tunable bandwidth, which greatly improves the performance of multilayer perceptrons for low-dimensional regression tasks.

Miniaturizing Ultrasonic System for Portable Health Care and Fitness
Hao-Yen Tang,Dongjin Seo,Utkarsh Singhal,Xi Li,Michel M. Maharbiz,Elad Alon,Bernhard E. Boser +6 more
TL;DR: A miniaturized portable ultrasonic imager that uses a custom ASIC and a piezoelectric transducer array to transmit and capture 2-D sonographs that can image human tissue as deep as 5 cm while consuming less than 16.5 μJ per pulse-echo measurement.
