What is Support Vector Machines?
Support Vector Machines (SVM) is a popular supervised machine learning algorithm used for both classification and regression tasks. It is based on the concept of finding an optimal hyperplane that separates data points into different classes or predicts a continuous value. SVM can handle both linearly separable and non-linearly separable data by using kernel functions to map the data into a higher-dimensional feature space.
How Support Vector Machines work
In SVM, each data point is represented as a multidimensional vector, and the algorithm aims to find the best hyperplane that maximizes the margin between different classes. The margin is the distance between the hyperplane and the closest data points from each class, called support vectors. By maximizing the margin, SVM aims to achieve better generalization and improved performance on unseen data.
SVM can handle both binary classification and multi-class classification tasks through various algorithms such as one-vs-one and one-vs-rest. It can also be extended to handle regression tasks by predicting a continuous value within a given range.
Why Support Vector Machines is important
Support Vector Machines offer several advantages that make them important in the field of machine learning and data analytics:
- Ability to handle high-dimensional feature spaces: SVM can effectively handle data with a large number of features, making it suitable for complex datasets.
- Robustness to outliers: SVM is less affected by outliers in the data compared to other algorithms, as it focuses on the support vectors close to the decision boundary.
- Flexibility with kernel functions: SVM allows the use of different kernel functions to transform the data into a higher-dimensional space, enabling the handling of non-linearly separable data.
- Good generalization and avoidance of overfitting: SVM aims to maximize the margin, which helps in achieving better generalization and avoiding overfitting.
