In this paper, we present two variations of an algorithm for signal reconstruction from one-bit or two-bit noisy observations of the discrete Fourier transform (DFT). The one-bit o…
Maintaining Ferment: On Opinion Control Over Social Networks
Mohak Goyal, Nikhil Karamchandani, Debasish Chatterjee +1
We consider the design of external inputs to achieve a control objective on the opinions, represented by scalars, in a social network. The opinion dynamics follow a variant of the…
