A Fast Granular-Ball-Based Density Peaks Clustering Algorithm for Large-Scale Data

2023 · IEEE Transactions on Neural Networks and Learning Systems

Density peaks clustering algorithm (DP) has difficulty in clustering large-scale data, because it requires the distance matrix to compute the density and -distance for each object, which has time complexity. Granular ball (GB) is a …

A Multi-Granularity Fireworks Algorithm with Collaboration and Competition for Solving the Influence Maximization Problem

2025

The Influence Maximization (IM) problem in social networks has been extensively studied, with greedy algorithms providing accurate and reliable solutions. However, their high computational cost renders them impractical for large-scale networks. Conversely, structure-based heuristic methods …
