Does svm benefit from feature scaling
Did you know?
WebAnswer (1 of 4): Actually it's not just algorithm dependent but also depends on your data. Normally you do feature scaling when the features in your data have ranges which vary wildly, so one objective of feature scaling is to ensure that when you use optimization algorithms such as gradient desc... SVM and Feature Scaling SVM is a supervised learning algorithm we use for classification and regression tasks. It is an effective and memory-efficient algorithm that we can apply in high-dimensional spaces. Training an SVM classifier includes deciding on a decision boundary between classes. See more In this tutorial, we’ll investigate the effects of feature scaling in the Support Vector Machine (SVM). First, we’ll learn about SVM and feature scaling. Then, we’ll illustrate the effect of … See more SVMis a supervised learning algorithm we use for classification and regression tasks.It is an effective and memory-efficient algorithm that we can apply in high-dimensional spaces.
