Abstract The objective of a community detection algorithm is to group similar nodes that are more connected to each other than with the rest of the network. Several methods have been proposed but many are of high complexity and require global knowledge of the network, which makes them less suitable for large-scale networks. The Label Propagation Algorithm initially assigns a distinct label to each node that iteratively updates its label with the one of the majority of its neighbors, until consensus is reached among all nodes in the network. Nodes sharing the same label are then grouped into communities. It runs in near linear time and is decentralized, but it gets easily stuck in local optima and often returns a single giant community. To overcome these problems we propose MemLPA, a variation of the classical Label Propagation Algorithm where each node implements a memory mechanism that allows them to “remember” about past states of the network and uses a decision rule that takes this information into account. We demonstrate through extensive experiments, on the Lancichinetti-Fortunato-Radicchi benchmark and a set of real-world networks, that MemLPA outperforms other existing label propagation algorithms that implement memory and some of the well-known community detection algorithms. We also perform a topological analysis to extend the performance study and compare the topological properties of the communities found to the ground-truth community structure.

Research in Moscow, New York, Paris, and Stockholm uncovers the compositional and early performance histories of Debussy’s ballet pantomime for children, The Toy Box. Surprisingly, the first large-scale production took place in Moscow, not Paris, and Henri Forterre—in advance of André Caplet—completed the orchestration after Debussy’s death. Theater directors and choreographers variously interpret Debussy’s distinctive approach to creating music for children as having been influenced by the designs of his scenarist, André Hellé. Although newly uncovered source materials might permit a reconstruction of The Toy Box, to do so would be to violate the spirit of the ballet, which embraces the imagined over the real and, paradoxically, the permanence of the ephemeral.
