Floorplanning with graph attention
Did you know?
WebWe propose a novel technique for constructing a floorplan from an adjacency requirement — represented by a graph G. The algorithm finds a geometric dual of G involving both rectangular and L-shaped modules. This is the first dualization technique which permits L-shaped modules. We can test in O ( n 3/2) time if G admits an L-shaped dual and ... WebConstrained Adjacency Graph (CAG), as indicated by its name, extends the adjacency graph corresponding to a dissected floorplan by adding constraints to its edges. More formally, Definition 1 (Constraitned Adjacency Graph): Suppose G = (V,E) is a directed graph with the vertices representing rooms and the edges representing adjacencies.
WebA rectangular floorplan construction problem is approached from a graph-theoretical view. The study is based on a reduction of the rectangular dualization problem to a matching problem on bipartite graphs. This opens the way to applying traditional graph-theoretic methods and algorithms to floorplanning. Another result is a method for generating … WebHere, we propose a novel Attention Graph Convolution Network (AGCN) to perform superpixel-wise segmentation in big SAR imagery data. AGCN consists of an attention mechanism layer and Graph Convolution Networks (GCN). GCN can operate on graph-structure data by generalizing convolutions to the graph domain and have been …
