作者展示了使用梯度下降且没有正则化的逻辑回归如何固有地将解决方案偏向最大边距分离器(也称为硬边距 SVM)。这是梯度下降的一个有趣且令人惊讶的行为。因为即使损失和优化不直接涉及任何鼓励边距最大化的术语(如您在支持向量机中发现的术语),梯度下降固有地将解决方案偏向最大边距分类器。H3 表示硬边界 SVM ...

The support vector machine (SVM) is a widely recognized learning algorithm used for both classification and regression tasks. Its main objective is to establish a decision boundary that maximizes the separation between class data points in the training set, thereby increasing the probability of ...

1. 如果Feature的数量很大,跟样本数量差不多,这时候选用LR或者是Linear Kernel的SVM 2. 如果Feature的数量比较小,样本数量一般,不算大也不算小,选用SVM+Gaussian Kernel 3. 如果Feature的数量比较小,而样本数量很多,需要手工添加一些feature变成第一种情况 ...
