Reconfigurable intelligent surface‐aided millimetre wave communications utilizing two‐phase minimax optimal stochastic strategy bandit

IET Communications, 2022
Millimetre wave (mmWave) communications, that is, 30 to 300 GHz, have intermittent short‐range transmissions, so the use of reconfigurable intelligent surface (RIS) seems to be a promising solution to extend its coverage. However, optimizing phase shifts

Consistent Sparse Deep Learning: Theory and Computation [PDF]

Journal of the American Statistical Association, 2021
Deep learning has been the engine powering many successes of data science. However, the deep neural network (DNN), as the basic model of deep learning, is often excessively over-parameterized, causing many difficulties in training, prediction and interpretation.

Computational reinforcement learning, reward (and punishment), and dopamine in psychiatric disorders

Frontiers in Psychiatry, 2022
In the DSM-5, psychiatric diagnoses are made based on self-reported symptoms and clinician-identified signs. Though helpful in choosing potential interventions based on the available regimens, this conceptualization of psychiatric diseases can limit ...
