While sequential behavior of single objects is fairly well understood, orchestrating the collective behavior emerging from the behaviors of individual objects continues to be a challenging task. This is especially true for distributed reactive systems. The joint action paradigm is a design methodology that concentrates on the collective behavior of objects. Aspects of collective behavior are gr...

In multiagent systems, social norms is a useful technique in regulating agents’ behaviors to achieve coordination or cooperation among agents. One important research question is to investigate how a desirable social norm can be evolved in a bottom-up manner through local interactions. In this paper, we propose two novel learning strategies under the collective learning framework: collective lea...

We describe the emergence of phase clustering and collective behaviors in an ensemble of chaotic coupled map lattices, due to a mean field interaction. This kind of interaction is responsible for the appearence of a collective state, wherein the mean field evolution of each lattice undergoes a periodic behavior in space. We analyze the transition to such a state in an ensemble of one-dimensiona...

User behaviors in social networks are microscopic with fine grained temporal information. Predicting a macroscopic quantity based on users’ collective behaviors is an important problem. However, existing works are mainly problem-specific models for the microscopic behaviors and typically design approximations or heuristic algorithms to compute the macroscopic quantity. In this paper, we propose...

CENTER FOR SEMIOTICS Recent approaches conceive of linguistic conversations as interpersonal synergies: In dialogue, interlocutors’ actions and cognitive processes become nonlinearly coupled and interdependent, enabling collective cognitive processes [1-3]. We apply complexity matching a measure of coupling across multiple time-scales to joint decision dialogues to investigate if interlocutors’...

While current GIS research has focused on technological issues of visualization and data organization, the emergence of new forms of collective authorship suggest we need new information frameworks and behaviors. How do individuals contribute place-based information to a digital commons? What are the authorship dynamics of such collective effort? For my research, I will use spatial data mining ...

Multiple mobile robots with six PSD (Position Sensitive Detector) sensors are designed for experimentally evaluating the performance of two control systems. They are self-control mode and server-supervisory control mode. The control systems are considered to realize swarm behaviors such as Ligia exotica. This is done by using only information of PSD sensors. Experimental results show basic but ...

AbstrAct Organizations must provide appropriate work group structures and communication technologies in order for work groups to function effectively and efficiently. This study investigated the hypotheses that team structure (e.g., fully collocated teams vs. virtual teams) and communication mode (i.e., face-to-face vs. videoconferencing) will impact virtual team group processes (e.g., team ori...

We argue that human economic interactions, particularly bargaining and trading in market environments, can be considered as collective social adaptive behaviors. Such interactions are social in the sense that they depend on socially-agreed market regulations and communication protocols, and are collective in the sense that global market dynamics depend on the interactions of groups of traders. ...
