## What is SVM :

Support Vector Machines (SVMs) are a type of supervised machine learning algorithm that can be used for classification or regression tasks. The goal of an SVM is to find the hyperplane in a high-dimensional space that maximally separates the different classes.

To better understand how SVMs work, let’s consider two examples:

Example 1: Classifying Email as Spam or Not Spam

Imagine that we have a dataset of emails, and we want to build a model to classify them as spam or not spam. One way to do this is to use an SVM.

First, we would need to extract features from the emails, such as the number of words, the presence of certain keywords, and the sender’s email address. These features would be used to represent each email as a point in a high-dimensional space.

Next, we would train the SVM by feeding it a labeled training dataset, where each email is labeled as either spam or not spam. The SVM would then try to find the hyperplane in this high-dimensional space that maximally separates the spam emails from the non-spam emails.

Once the model is trained, we can then use it to classify new emails as either spam or not spam by feeding them into the model and seeing which side of the hyperplane they fall on.

Example 2: Predicting Housing Prices

Another example of using an SVM is to predict housing prices based on a variety of features, such as the size of the house, the number of bedrooms, the location, etc.

Again, we would first extract the relevant features from the data and represent each house as a point in a high-dimensional space. We would then train an SVM on a labeled training dataset, where each house is labeled with its actual price.

The SVM would then try to find the hyperplane in this space that maximally separates the houses with high prices from those with low prices. Once the model is trained, we can use it to predict the prices of new houses by feeding them into the model and seeing which side of the hyperplane they fall on.

While this may seem like a simple task, it can be quite challenging in practice due to the high-dimensional nature of the data and the complexity of the real estate market. However, SVMs are known for their ability to handle high-dimensional data and can be very effective in predicting housing prices.

Conclusion :

In summary, SVMs are a powerful tool for classification and regression tasks that can handle high-dimensional data and find the hyperplane that maximally separates different classes. They are commonly used in a variety of applications, including spam filtering, image classification, and predicting housing prices.
