Constraint-Induced Symmetric Nonnegative Matrix Factorization for Accurate Community Detection

1 code implementation journal 2023 ZhiGang Liu, Xin Luo, Zidong Wang, Xiaohui Liu

Motivated by this discovery, this paper proposes a novel Constraintinduced Symmetric Nonnegative Matrix Factorization (C-SNMF) model that adopts three-fold ideas: a) Representing a target undirected network with multiple latent feature matrices, thus preserving its representation learning capacity; b) Incorporating a symmetry-regularizer into its objective function, which preserves the symmetry of the learnt low-rank approximation to the adjacency matrix, thereby making the resultant detector precisely illustrate the target network’s symmetry; and c) Introducing a graph-regularizer that preserves local invariance of the network’s intrinsic geometry into its learning objective, thus making the achieved detector well-aware of community structure within the target network.

An Effective and Efficient Evolutionary Algorithm for Many-Objective Optimization

no code implementations31 May 2022 Yani Xue, Miqing Li, Xiaohui Liu

In such problems, classic Pareto-based algorithms fail to provide sufficient selection pressure towards the Pareto front, whilst recently developed algorithms, such as decomposition-based ones, may struggle to maintain a set of well-distributed solutions on certain problems (e. g., those with irregular Pareto fronts).
