Fuzzy support vector data description based on vague sets

Abstract

Abstract: To resolve the problem of over-fitted caused by noises and outliers in support vector data description, fuzzy support vector data description based on vague sets（VFSVDD） is proposed in this paper. Fuzzy k-means clustering algorithm is employed for generating the truth-membership and false-membership, how each training example affects the boundary of hypersphere could be controlled. Test data from UCI machine learning repository are employed to evaluate the usefulness of VFSVDD.

摘要： 针对支持向量数据描述中噪声和孤立点带来的过拟合问题，提出了一种Vague集的支持向量数据描述（VFSVDD），利用模糊k-均值聚类方法生成每个训练样本的真、假隶属度，可以精细地控制训练样本对超球面边界的影响。用UCI机器学习数据集的数据实验验证了VFSVDD的有效性。
