Support Vector Machines (SVM) are powerful supervised learning algorithms used for classification and regression tasks. This tutorial will guide you through implementing SVM in Python using popular libraries like scikit-learn.

Key Concepts of SVM

  1. Maximum Margin 📈
    SVM aims to find the optimal hyperplane that maximizes the margin between different classes.

    Support Vector Machine

  2. Kernel Trick 🧠
    The kernel method allows SVM to handle non-linear data by transforming it into higher-dimensional spaces.

  3. Types of SVM 📚

    • Linear SVM (for linearly separable data)
    • Non-linear SVM (using kernel functions)
    Data Classification

Python Implementation Example

Here's a simple code snippet to train an SVM classifier: 

from sklearn.svm import SVC  
from sklearn.datasets import make_classification  
from sklearn.model_selection import train_test_split  

# Generate synthetic data  
X, y = make_classification(n_samples=100, n_features=2, n_informative=2, n_redundant=0, random_state=42)  
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)  

# Train SVM model  
model = SVC(kernel='linear')  
model.fit(X_train, y_train)  

# Evaluate model  
accuracy = model.score(X_test, y_test)  
print(f"Model Accuracy: {accuracy:.2f}")
