Differentially Quantized Gradient Methods
Chung-Yi Lin, Victoria Kostina, Babak Hassibi
Consider the following distributed optimization scenario. A worker has access to training data that it uses to compute the gradients while a server decides when to stop iterative c…
Optimal Causal Rate-Constrained Sampling for a Class of Continuous Markov Processes
Nian Guo, Victoria Kostina
Consider the following communication scenario. An encoder observes a stochastic process and causally decides when and what to transmit about it, under a constraint on the expected…
Gaussian Multiple and Random Access in the Finite Blocklength Regime
Recep Can Yavas, Victoria Kostina, Michelle Effros
This paper presents finite-blocklength achievability bounds for the Gaussian multiple access channel (MAC) and random access channel (RAC) under average-error and maximal-power con…
