Graph pooling with representativeness
WebNov 1, 2024 · To enhance node representativeness, the output of each convolutional layer is concatenated with the output of the previous layer’s readout to form a global context-aware node representation. ... Considering graph readout/pooling operations, the most basic operations are simple statistics like taking the sum, mean or max-pooling. … WebJul 1, 2024 · The LRNet algorithm for the construction of the weighted graph utilizing local representativeness is composed of four steps: 1. Create a similarity matrix S of dataset D. 2. Calculate the representativeness of all objects \(O_i\). 3. Create the set V of nodes of graph G so that node \(v_i\) of graph G represents object \(O_i\) of dataset D. 4.
