1)rare classes稀有类
1.Based on the research of technology to classify rare classes, an approach based on ensemble learning is proposed.针对现有的网络入侵检测算法对少数类攻击的检测存在高误报率和漏报率的问题,在对稀有类分类技术研究的基础上,将集成学习应用到入侵检测中。
2.AUC-Based boosting method for the classification of rare classes;由于不平衡数据集中多数类与稀有类的数量相差较大,所以大多数分类算法都不能够很好地对稀有类样本进行分类,而通常稀有类才是我们首要关心的,这就给不平衡数据的分类提出了挑战,为了更好地处理不平衡数据集的分类问题,本文提出了一种以基分类器的ROC曲线下面积(AUC面积)为分类权重的AUCBoost分类算法。

C24类甾醇类分子式：CAS号：性质：胆汁酸属于类甾(或固)醇类，又称为C24类甾醇类。正常人胆汁中有结合胆汁酸和游离胆汁酸两大类，并以前者为主。游离胆汁酸有胆酸、脱氧胆酸和鹅脱氧胆酸等；结合胆汁酸系指上述胆汁酸以酰胺键(简称肽键)与甘氨酸或牛磺酸结合，分别成为甘氨胆酸或牛磺胆酸等。这些化合物存在于大多数脊椎动物中，是“胆苦”的主要成分。结合胆汁酸易溶于水，这是由于其分子中既含有亲水的羟基和羧基，又含有疏水的甲基，且这两种性质不同的基团又完全排列在环戊烷多氢菲核的两侧，使分子分为“亲水”和“疏水”两个侧面。故结合胆汁酸具有强乳化剂功能，使肠腔内油脂乳化成微粒，以增加油脂与消化液中脂肪酶(lipase)接触面积而便于脂类消化吸收，同时也促进对脂溶性维生素的吸收。
