Load Balancing with Partial Queue Information - Threshold Optimality and Indexability
Sathwik Chadaga, Eytan Modiano
We consider the problem of load balancing in a system with one dispatcher and parallel servers. The dispatcher must select one server to dispatch new jobs at every time-step an…
Faster-Than-Nyquist Signalling -- Theoretical Limits on Capacity and Techniques to Approach Capacity
Sathwik Chadaga
Faster-Than-Nyquist (FTN) Signalling is a non-orthogonal transmission scheme that violates the Nyquist zero-ISI criterion providing higher throughput and better spectral efficiency…
Drift Plus Optimistic Penalty: A Learning Framework for Stochastic Network Optimization with Improved Regret Bounds
Sathwik Chadaga, Eytan Modiano
We consider the problem of joint routing and scheduling in queueing networks, where the edge transmission costs are unknown. At each time-slot, the network controller receives nois…
Power Failure Cascade Prediction using Graph Neural Networks
Sathwik Chadaga, Xinyu Wu, Eytan Modiano
We consider the problem of predicting power failure cascades due to branch failures. We propose a flow-free model based on graph neural networks that predicts grid states at every…
Encoders and Decoders for Quantum Expander Codes Using Machine Learning
Sathwik Chadaga, Mridul Agarwal, Vaneet Aggarwal
Quantum key distribution (QKD) allows two distant parties to share encryption keys with security based on laws of quantum mechanics. In order to share the keys, the quantum bits ha…
