Supervised Learning - Classification Week 7 Challenge
Answer 1
Pros:
Effective in High-Dimensional Spaces: SVMs work well in high-dimensional spaces, making them suitable for tasks like image classification.
Versatile Kernel Options: SVMs allow the use of different kernel functions, such as linear, polynomial, and radial basis function (RBF), providing flexibility in capturing complex relationships.
Robust to Overfitting: SVMs aim to maximize the margin between classes, which can help prevent overfitting, especially in cases of noisy data.
Global Optimization: SVMs use convex optimization, ensuring the model finds the global minimum rather than getting stuck in local minima.
Works well with Small/Medium-Sized Datasets: SVMs can be effective even when the dataset is not massive, making them suitable for scenarios with limited data.
Cons:
Computationally Intensive: SVMs can be computationally expensive, especially with large datasets. Training time can increase significantly as the dataset size grows.
Sensitivity to Noise: SVMs can be sensitive to noisy data, affecting the model's performance. Data preprocessing is crucial to mitigate this issue.
Difficulty in Parameter Selection: Choosing appropriate parameters, such as the regularization parameter and kernel parameters, can be challenging and may require careful tuning.
Binary Classification: SVMs are inherently binary classifiers. While there are extensions for multiclass problems, they might not perform as naturally as in binary cases.
Limited Interpretability: SVMs are often considered as "black box" models, making it challenging to interpret the learned decision boundaries, especially in high-dimensional spaces.
