Support Vector Machines

Support vector machines(SVMs) are supervised learning models with associated learning algorithms that analyze data and recognize patterns used for classification and regression analysis.


Advantages:

  • Effective in high dimensional space
  • Still effective in cases where no. of dimensional is greater than no. of samples.
  • Uses a subset of training points in the decision function. So it is also memory efficient.
  • Versatile: different kernal functions can be specified for the decision function. Common kernals are provided. But it also possible to specify custom kernals.
