Salvatore Citraro - "Tools for Node-Attributed Community Detection"
Abstract: Node-attributed community detection aims to identify cohesive clusters in graphs with label homogeneity among their nodes. This presentation sums up two studies that we carried out to advance the field of clustering in network science. The first work introduces a novel algorithm, EVA, which balances structural cohesion and label homogeneity when identifying communities. The second work introduces a graph benchmark, X-Mark, which generates synthetic node-attributed graphs with planted communities to test the goodness of clustering algorithms.
Being this presentation specifically tailored for the Young Researcher Award ISTI event, I intend not only to present technical details and results of our work, but also discuss its potential impact. Being us "young researchers", we acknowledge that the scientific impact of our work might still be in its infancy. I try to examine how other researchers -- far away from our network of collaborators -- have utilized our tools in their work, reflecting on the practical value and relevance of our contributions.
Francesco Laccone - "Turning polygonal meshes into efficient structures"
Abstract: Architectural surfaces, used as roofs, façades, and free-standing structures, are often employed to achieve spectacular effects and catch the user's attention as proper artworks. In real world applications, the design constraints are manifold, ranging from manufacturing and material tools, to the sculptural shape and support conditions given by the lead designer. Several research directions investigate how to explore a fixed design space to build complex objects that look and perform in a desired way and use a specific material or structural concept. This talk will overview some recent advancements on the use of polygonal tessellations as structural grids, and the methods and tools that streamline their design. In particular, the common basis for the presented methodologies is the adaptability of Voronoi meshes to specific structural requirements in shells and tall building skins.
