Attention-Based Clustering: Learning a Kernel from Context
Samuel Coward, Erik Visse-Martindale, Chithrupa Ramesh
In machine learning, no data point stands alone. We believe that context is an underappreciated concept in many machine learning methods. We propose Attention-Based Clustering (ABC…
Sufficient Optimality Conditions for Distributed, Non-Predictive Ramp Metering in the Monotonic Cell Transmission Model
Marius Schmitt, Chithrupa Ramesh, John Lygeros
We consider the ramp metering problem for a freeway stretch modeled by the Cell Transmission Model. Assuming perfect model knowledge and perfect traffic demand prediction, the ramp…
Distributed Learning in the Presence of Disturbances
Chithrupa Ramesh, Marius Schmitt, John Lygeros
We consider a problem where multiple agents must learn an action profile that maximises the sum of their utilities in a distributed manner. The agents are assumed to have no knowle…
Separated design of encoder and controller for networked linear quadratic optimal control
Maben Rabi, Chithrupa Ramesh, Karl Henrik Johansson
For a networked control system, we consider the problem of encoder and controller design. We study a discrete-time linear plant with a finite horizon performance cost, comprising o…
Stability Analysis and Design of a Network of Event-based Systems
Chithrupa Ramesh, Henrik Sandberg, Karl H. Johansson
We consider a network of event-based systems that use a shared wireless medium to communicate with their respective controllers. These systems use a contention resolution mechanism…
Performance Analysis of a Network of Event-based Systems
Chithrupa Ramesh, Henrik Sandberg, Karl H. Johansson
We consider a scenario where multiple event-based systems use a wireless network to communicate with their respective controllers. These systems use a contention resolution mechani…
Design of State-based Schedulers for a Network of Control Loops
Chithrupa Ramesh, Henrik Sandberg, Karl H. Johansson
For a closed-loop system, which has a contention-based multiple access network on its sensor link, the Medium Access Controller (MAC) may discard some packets when the traffic on t…
Network Estimation and Packet Delivery Prediction for Control over Wireless Mesh Networks
Phoebus Chen, Chithrupa Ramesh, Karl H. Johansson
Much of the current theory of networked control systems uses simple point-to-point communication models as an abstraction of the underlying network. As a result, the controller has…
