Analysis of Strategy and Spread of Russia-sponsored Content in the US in 2017
Alexander Spangher, Gireeja Ranade, Besmira Nushi +2
The Russia-based Internet Research Agency (IRA) carried out a broad information campaign in the U.S. before and after the 2016 presidential election. The organization created an ex…
Exact minimum number of bits to stabilize a linear system
Victoria Kostina, Yuval Peres, Gireeja Ranade +1
We consider an unstable scalar linear stochastic system, , where is the system gain, 's are independent random variables with bounded …
Wireless Channel Dynamics and Robustness for Ultra-Reliable Low-Latency Communications
Vasuki Narasimha Swamy, Paul Rigge, Gireeja Ranade +2
Interactive, immersive and critical applications demand ultra-reliable low-latency communication (URLLC). To build wireless communication systems that can support these application…
Stabilizing a system with an unbounded random gain using only a finite number of bits
Victoria Kostina, Yuval Peres, Gireeja Ranade +1
We study the stabilization of an unpredictable linear control system where the controller must act based on a rate-limited observation of the state. More precisely, we consider the…
Stabilizing a linear system using phone calls when time is information
Mohammad Javad Khojasteh, Massimo Franceschetti, Gireeja Ranade
We consider the problem of stabilizing an undisturbed, scalar, linear system over a "timing" channel, namely a channel where information is communicated through the timestamps of t…
Network Coding for Real-time Wireless Communication for Automation
Vasuki Narasimha Swamy, Paul Rigge, Gireeja Ranade +2
Real-time applications require latencies on the order of a millisecond with very high reliabilities, paralleling the requirements for high-performance industrial control. Current w…
Verifying Controllers Against Adversarial Examples with Bayesian Optimization
Shromona Ghosh, Felix Berkenkamp, Gireeja Ranade +2
Recent successes in reinforcement learning have lead to the development of complex controllers for real-world robots. As these robots are deployed in safety-critical applications a…
