Linear Algebra for Machine Learning 🤖

Key Concepts 🧮

Linear algebra forms the backbone of machine learning algorithms. Here are core topics to master:

• Vectors 📏: Represent data points or features (e.g., x = [1, 2, 3] in Python).
• Matrices 🧮: Organize data in 2D arrays (e.g., weight matrices in neural networks).
• Eigenvalues & Eigenvectors 🔍: Critical for dimensionality reduction and PCA.
• Matrix Multiplication 📦: Fundamental for transforming data (e.g., A * B operations).

Applications in Machine Learning 📊

1. Data Representation 🗂️: Vectors and matrices store datasets efficiently.
2. Principal Component Analysis (PCA) 🔄: Reduces dimensionality using eigenvectors.
3. Neural Networks 🤖: Weights are updated via matrix multiplication in backpropagation.
4. Image Processing 🖼️: Pixels are treated as matrices for transformations.
