## How does SVM algorithm work?

SVM is a supervised machine learning algorithm which can be used for classification or regression problems. It uses a technique called the kernel trick to transform your data and then based on these transformations it finds an optimal boundary between the possible outputs.

## How do you implement a support vector machine?

Implementing SVM in Python

1. Importing the dataset.
2. Splitting the dataset into training and test samples.
3. Classifying the predictors and target.
4. Initializing Support Vector Machine and fitting the training data.
5. Predicting the classes for test set.
6. Attaching the predictions to test set for comparing.

What is Support Vector Machine geeks for geeks?

Support Vector Machine (SVM) is a relatively simple Supervised Machine Learning Algorithm used for classification and/or regression. It is more preferred for classification but is sometimes very useful for regression as well. Basically, SVM finds a hyper-plane that creates a boundary between the types of data.

### How are the Support Vector Machine useful for categories the data?

A support vector machine allows you to classify data that’s linearly separable. If it isn’t linearly separable, you can use the kernel trick to make it work. However, for text classification it’s better to just stick to a linear kernel.

### When should you use SVM?

I would suggest you go for linear SVM kernel if you have a large number of features (>1000) because it is more likely that the data is linearly separable in high dimensional space. Also, you can use RBF but do not forget to cross-validate for its parameters to avoid over-fitting.

What are SVM good for?

Support vector machines (SVMs) are a set of supervised learning methods used for classification, regression and outliers detection. The advantages of support vector machines are: Effective in high dimensional spaces. Still effective in cases where number of dimensions is greater than the number of samples.
