ABSTRACT = {In recent years, the soft subspace clustering algorithm has shown good results for high-dimensional data, which
can assign different weights to each cluster class and use weights to measure the contribution of each dimension
in various features. The enhanced soft subspace clustering algorithm combines interclass separation and intraclass
tightness information, which has strong results for image segmentation, but the clustering algorithm is vulnerable
to noisy data and dependence on the initialized clustering center. However, the clustering algorithm is susceptible to
the influence of noisy data and reliance on initialized clustering centers and falls into a local optimum; the clustering
effect is poor for brain MR images with unclear boundaries and noise effects. To address these problems, a soft
subspace clustering algorithm for brain MR images based on genetic algorithm optimization is proposed, which
combines the generalized noise technique, relaxes the equational weight constraint in the objective function as the
boundary constraint, and uses a genetic algorithm as a method to optimize the initialized clustering center. The
genetic algorithm finds the best clustering center and reduces the algorithm’s dependence on the initial clustering
center. The experiment verifies the robustness of the algorithm, as well as the noise immunity in various ways and
shows good results on the common dataset and the brain MR images provided by the Changshu First People’s
Hospital with specific high accuracy for clinical medicine.},
