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…
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…
Estimating True Beliefs in Opinion Dynamics with Social Pressure
Jennifer Tang, Aviv Adler, Amir Ajorlou +1
Social networks often exert social pressure, causing individuals to adapt their expressed opinions to conform to their peers. An agent in such systems can be modeled as having a (t…
Stochastic Opinion Dynamics under Social Pressure in Arbitrary Networks
Jennifer Tang, Aviv Adler, Amir Ajorlou +1
Social pressure is a key factor affecting the evolution of opinions on networks in many types of settings, pushing people to conform to their neighbors' opinions. To study this, th…
Demystifying Oversmoothing in Attention-Based Graph Neural Networks
Xinyi Wu, Amir Ajorlou, Zihui Wu +1
Oversmoothing in Graph Neural Networks (GNNs) refers to the phenomenon where increasing network depth leads to homogeneous node representations. While previous work has established…
Competitive Contagion with Sparse Seeding
Milad Siami, Amir Ajorlou, Ali Jadbabaie
This paper studies a strategic model of marketing and product diffusion in social networks. We consider two firms offering substitutable products which can improve their market sha…
Sales-Based Rebate Design
Amir Ajorlou, Ali Jadbabaie
We propose a novel family of sales-based rebate mechanisms that induce network effects in sales of products that do not exhibit such externalities. The proposed rebate mechanisms e…
Digraphs with Distinguishable Dynamics under the Multi-Agent Agreement Protocol
M. Amin Rahimian, Amir Ajorlou, Amir G. Aghdam
In this work, the ability to distinguish digraphs from the output response of some observing agents in a multi-agent network under the agreement protocol has been studied. Given a…
Local Optimality of Almost Piecewise-Linear Quantizers for Witsenhausen's Problem
Amir Ajorlou, Ali Jadbabaie
We pose Witsenhausen's problem as a leader-follower game of incomplete information. The follower makes a noisy observation of the leader's action (who moves first) and chooses an a…
Competitive Diffusion in Social Networks: Quality or Seeding?
Arastoo Fazeli, Amir Ajorlou, Ali Jadbabaie
In this paper, we study a strategic model of marketing and product consumption in social networks. We consider two firms in a market competing to maximize the consumption of their…
Optimal Budget Allocation in Social Networks: Quality or Seeding
Arastoo Fazeli, Amir Ajorlou, Ali Jadbabaie
In this paper, we study a strategic model of marketing and product consumption in social networks. We consider two competing firms in a market providing two substitutable products…
