Will present a talk entitled:

Detecting Cluster Synchronization via Causation Entropy in Chaotic Networks

Abstract: The complex networks formed by interactions of identical or similar dynamical systems allow us to model various natural and artificial phenomena. It is not surprising that modeling and analyzing such complex networks in physical, biological, engineering, and social sciences is a subject of ongoing interest. When interacting systems are chaotic, they exhibit unpredictable behavior due to their sensitive dependence on initial conditions and parameters. Moreover, when chaotic systems are coupled to each other through state variables, synchronization can happen. The cluster synchronization phenomenon, in which groups of coupled dynamical systems synchronize without complete synchronization of all systems in the network, is especially interesting. In this talk, we aim to detect of clusters via information measures in continuous coupled chaotic networks. The results have shown that causation entropies estimated from observations can be used to determine the number of synchronous clusters and membership information of the network elements in a chaotic network. Therefore, the average integrated causation measure and a novel algorithm have been demonstrated to detect the clusters. The proposed procedure has been tested on various chaotic networks. The ultimate goal of this study will be to develop the network reconstruction of the cluster synchronization for directional or bidirectional networks and enlighten us to understand the complex networks.

The poster is designed to promote the "CUGSA Executive Board Elections 2024" and is visually engaging, using a color palette of deep green, yellow, and hints of red. The top section of the poster features a deep green background with bold, white text that reads "CUGSA EXECUTIVE BOARD ELECTIONS 2024" and below this, "VOTE NOW" alongside a QR code for easy access to voting information or the voting site. The middle section of the poster marks the election dates, "MAY 2-3, 2024," prominently displayed against a bright yellow background that contrasts with the green above. The bottom part of the poster is particularly lively and illustrative. It features a large, red ballot box labeled "VOTE" on its side. There are two animated characters interacting with the ballot box. The first character, a man, is standing on top of the box and speaking into a megaphone, symbolizing active participation or rallying for votes. The second character, a woman, is next to the ballot box, holding up a ballot paper as if she is about to drop it into the box, representing the act of voting. The background includes simplistic representations of clouds and stars, adding a playful element to the scene. The poster is finished with the logo of the Clarkson University Graduate Student Association (CUGSA) at the bottom, anchoring the poster with a sense of official endorsement and identity. This design effectively communicates the essential information about the election while encouraging active participation through its vibrant and dynamic visuals.
