理: L1_norm:所有样本数据的绝对值求和作为分母;样本数据作为分子。将样本数据映射到(-1,1)区间。 L2_norm:所有样本数据求平方和后开根号作为分母;样本数据作为分子。将样本数据映射到(-1,1)区间。 标准化操作步骤如下。 单击表头,选中需要执行标准化的特征列。 选中的特征列必须为数值型。
By using two smooth convex penalty functions, based on Kullback-Leibler divergence (KL) and l2 norm, we derive two new regularized AdaBoost algorithms, referred to as AdaBoostKL and AdaBoostNorm2, respectively. We prove that our algorithms perform stage-wise gradient descent on a cost function...

范数(norm)是数学中的一种基本概念,定义为赋范线性空间中的一种函数,满足以下三个条件: 非负性:对于所有向量x,有||x|| ≥ 0,且||x|| = 0当且仅当x = 0。 齐次性:对于所有实数a和向量x,有||ax|| = |a|·||x||。
