How to Query An Oracle? Efficient Strategies to Label Data
Farshad Lahouti, Victoria Kostina, Babak Hassibi
We consider the basic problem of querying an expert oracle for labeling a dataset in machine learning. This is typically an expensive and time consuming process and therefore, we s…
Reducing the LQG Cost with Minimal Communication
Oron Sabag, Peida Tian, Victoria Kostina +1
We study the linear quadratic Gaussian (LQG) control problem, in which the controller's observation of the system state is such that a desired cost is unattainable. To achieve the…
Feedback Capacity of MIMO Gaussian Channels
Oron Sabag, Victoria Kostina, Babak Hassibi
Finding a computable expression for the feedback capacity of channels with colored Gaussian, additive noise is a long standing open problem. In this paper, we solve this problem in…
Variable-Length Sparse Feedback Codes for Point-to-Point, Multiple Access, and Random Access Channels
Recep Can Yavas, Victoria Kostina, Michelle Effros
This paper investigates variable-length stop-feedback codes for memoryless channels in point-to-point, multiple access, and random access communication scenarios. The proposed code…
Instantaneous SED coding over a DMC
Nian Guo, Victoria Kostina
In this paper, we propose a novel code for transmitting a sequence of message bits in real time over a discrete-memoryless channel (DMC) with noiseless feedback, where the mess…
