chordal distance

Firstly,distances between unlabeled samples and the hyperplane are calculated,and cosine distance sum form unlabeled samples to samples in current training data is calculated.

为解决基于内容的图像检索中训练集样本过小问题,本文提出一种结合相关反馈和支持向量机的主动学习算法,首先计算未标注样本到分类超平面的距离以及与当前训练集中样本的余弦距离和,然后取具有总的最大余弦距离同时到超平面距离最短的样本加入训练集,通过增加最具信息的样本到训练集,使得分类器可通过少量反馈次数而快速达到较高的准确性。

This article interview a new style of composite slab,based on the comparing of a trial,found a correct finite element model,the influence of 2 parameters to the short-term rigidity of precast slab is analyzed,one is the axis distance between the top member and the bottom member,the other is the radius of web member.
