Next-token functional estimation
Milind Nakul, Vidya Muthukumar, Ashwin Pananjady
Suppose we observe the first points of a sequence of random variables having length , and wish to estimate a functional of the unobserved final point and the empirical mea…
Multiscale replay: A robust algorithm for stochastic variational inequalities with a Markovian buffer
Milind Nakul, Tianjiao Li, Ashwin Pananjady
We introduce the Multiscale Experience Replay (MER) algorithm for solving a class of stochastic variational inequalities (VIs) in settings where samples are generated from a Markov…
Estimating stationary mass, frequency by frequency
Milind Nakul, Vidya Muthukumar, Ashwin Pananjady
Suppose we observe a trajectory of length from an exponentially -mixing stochastic process over a finite but potentially large state space. We consider the problem of estima…
Variational Learning Algorithms For Channel Estimation in RIS-assisted mmWave Systems
Milind Nakul, Anupama Rajoriya, Rohit Budhiraja
We consider the problem of estimating the channel in reconfigurable intelligent surface (RIS) assisted millimeter wave (mmWave) systems. We propose two variational expectation maxi…
