Optimal estimation in spatially distributed systems: how far to share measurements from?
Juncal Arbelaiz, Bassam Bamieh, Anette E. Hosoi +1
We consider the centralized optimal estimation problem in spatially distributed systems. We use the setting of spatially invariant systems as an idealization for which concrete and…
Residual Connections and Normalization Can Provably Prevent Oversmoothing in GNNs
Michael Scholkemper, Xinyi Wu, Ali Jadbabaie +1
Residual connections and normalization layers have become standard design choices for graph neural networks (GNNs), and were proposed as solutions to the mitigate the oversmoothing…
On the Role of Attention Masks and LayerNorm in Transformers
Xinyi Wu, Amir Ajorlou, Yifei Wang +2
Self-attention is the key mechanism of transformers, which are the essential building blocks of modern foundation models. Recent studies have shown that pure self-attention suffers…
A least-square method for non-asymptotic identification in linear switching control
Haoyuan Sun, Ali Jadbabaie
The focus of this paper is on linear system identification in the setting where it is known that the underlying partially-observed linear dynamical system lies within a finite coll…
Belief Samples Are All You Need For Social Learning
Mahyar JafariNodeh, Amir Ajorlou, Ali Jadbabaie
In this paper, we consider the problem of social learning, where a group of agents embedded in a social network are interested in learning an underlying state of the world. Agents…
