网络释义

用法例句

The method firstly organizes support vectors in clusters in feature space, and then,it finds the pre-images of the cluster centroids in feature spa.

此方法首先在特征空间中对支持向量进行聚类,然后寻找特征空间中的聚类中心在输入空间中的原像以形成约简向量集。

The method first oversamples the minority class in feature space by kernel SMOTE algorithm,then the pre-images of the synthetic instances are found based on a distance relation between feature space and input space.

其核心思想是首先在特征空间中采用核SMOTE方法对少数类样本进行上采样,然后通过输入空间和特征空间的距离关系寻找所合成样本在输入空间的原像,最后再采用SVM对其进行训练。

For each cluster centroid,it finds the pre-image in input space and adopts it as a reduced vector to compress the number of support vectors.

针对该问题提出一种新的SVM约简方法,在特征空间中对支持向量进行聚类,寻找聚类质心在输入空间中的原像,将其作为约简向量,以实现支持向量削减目的。
