Equivariant Priors for Compressed Sensing with Unknown Orientation

no code implementations28 Jun 2022 Anna Kuzina, Kumar Pratik, Fabio Valerio Massoli, Arash Behboodi

In compressed sensing, the goal is to reconstruct the signal from an underdetermined system of linear measurements.

Neural Augmentation of Kalman Filter with Hypernetwork for Channel Tracking

no code implementations26 Sep 2021 Kumar Pratik, Rana Ali Amjad, Arash Behboodi, Joseph B. Soriaga, Max Welling

Through extensive experiments on CDL-B channel model, we show that the HKF can be used for tracking the channel over a wide range of Doppler values, matching Kalman filter performance with genie Doppler information.

RE-MIMO: Recurrent and Permutation Equivariant Neural MIMO Detection

1 code implementation30 Jun 2020 Kumar Pratik, Bhaskar D. Rao, Max Welling

Each iterative unit is a neural computation module comprising of 3 sub-modules: the likelihood module, the encoder module, and the predictor module.
