特征选择之relief-F的MATLAB实现
Relief-F 算法是由 Kononenko 在 Relief 算法基础上扩展得到的，可以用来解决多分类与回归问题。 Relief-F 特征选择算法利用特征与类别间的相关程度判别特征的敏感程度，敏感的特征能使同类样本靠近，非同类样本远离。基本思想是： 先随机从总样本集 D中获取一个样本 R， 然后在 与 R 同类样本集中和与R 异类 样 本 集 中 各 获 取 k 个近 邻 样 本， 在 特 征 集 F中如果某个特征上异类样本的距离大于同类样本，则这个特征是有利于分类的，增加其权重，重复 n 次 取所有结果的均值作为每个特征的最终权重值.

Abstract—Noninvasive ultrasound imaging of carotid plaques
allows for the development of plaque-image analysis methods associated
with the risk of stroke. This paper presents several plaqueimage
analysis methods that have been developed over the past
years. The paper begins with a review of clinical methods for visual
classification that have led to standardized methods for image
acquisition, describes methods for image segmentation and denoizing,
and provides an overview of the several texture-feature
extraction and classification methods that have been applied. We
provide a summary of emerging trends in 3-D imaging methods
and plaque-motion analysis. Finally, we provide a discussion of the
emerging trends and future directions in our concluding remarks.
