The Artificial Fish Swarm Algorithm (AFSA) is inspired by the ecological behaviors of fish schooling in nature, viz., the preying, swarming and following behaviors. Owing to a number of salient properties, which include flexibility, fast convergence, and insensitivity to the initial parameter settings, the family of AFSA has emerged as an effective Swarm Intelligence (SI) methodology that has been widely applied to solve real-world optimization problems. Since its introduction in 2002, many improved and hybrid AFSA models have been developed to tackle continuous, binary, and combinatorial optimization problems. This paper aims to present a concise review of the continuous AFSA, encompassing the original ASFA, its improvements and hybrid models, as well as their associated applications. We focus on articles published in high-quality journals since 2013. Our review provides insights into AFSA parameters modifications, procedure and sub-functions. The main reasons for these enhancements and the comparison results with other hybrid methods are discussed. In addition, hybrid, multi-objective and dynamic AFSA models that have been proposed to solve continuous optimization problems are elucidated. We also analyse possible AFSA enhancements and highlight future research directions for advancing AFSA-based models. Copyright © 2020, The Authors. All rights reserved.

Exploiting lab.l correlations is important to multi-lab.l classification. Previous methods capture the high-order lab.l correlations mainly by transforming the lab.l matrix to a latent lab.l space with low-rank matrix factorization. However, the lab.l matrix is generally a full-rank or approximate full-rank matrix, making the low-rank factorization inappropriate. Besides, in the latent space, the lab.l correlations will become implicit. To this end, we propose a simple yet effective method to depict the high-order lab.l correlations explicitly, and at the same time maintain the high-rank of the lab.l matrix. Moreover, we estimate the lab.l correlations and infer model parameters simultaneously via the local geometric structure of the input to achieve mutual enhancement. Comparative studies over twelve benchmark data sets validate the effectiveness of the proposed algorithm in multi-lab.l classification. The exploited high-order lab.l correlations are consistent with common sense empirically. Our code is publicly availab.e at https://***/Chongjie-Si/HOMI. Copyright © 2022, The Authors.
