In machine learning, what is the main purpose of using a support vector machine (SVM)
分类问题:SVM 主要用于解决二分类问题,可以通过调整参数和选择合适的核函数来适应不同的数据特征。 回归分析:SVM 还可以应用于回归分析问题,称为支持向量回归(Support Vector Regression,SVR),通过最小化预测值与真实值之间的误差来拟合数据。 异常检测:SVM 还可以用于异常检测,通过找到与训练样本差异较大的数据点来识...
Support Vector Machine (SVM) algorithm in python & machine learning is a simple yet powerful Supervised ML algorithm that can be used for both regression & classification models.
Support Vector Machine (SVM) in Machine Learning - Support vector machines (SVMs) are powerful yet flexible supervised machine learning algorithm which is used for both classification and regression. But generally, they are used in classification problem

(2)re-scale the margin。这个方法由Taskar针对于Hamming loss提出, 至此,我们已经建立好了SVM模型。 接下来作者便看是进行Support Vector Machine learning。这块好难啊!
