A novel multi-level image segmentation algorithm via random opposition learning-based Aquila optimizer

2023 · International Journal of Wavelets Multiresolution and Information Processing

Aquila optimizer (AO) is an efficient meta-heuristic optimization method, which mimics the hunting style of Aquila in nature. However, the AO algorithm may suffer from immature convergence during the exploitation stage. In this paper, two …

Noise Perturbation Based Graph Contrastive Learning via Flexible Filters for Node Classification

2024

Graph neural networks (GNNs), as a powerful deep learning framework for modeling graph-structured data, have attracted lots of attention recently. Most of existing GNNs need a lot of labeled data. However, constructing generalizable and robust …
