Linear algebra is a foundational branch of mathematics essential for data science, machine learning, and engineering. It deals with vectors, matrices, and linear transformations. Let's explore key concepts!
Core Concepts 📚
- Vectors: Quantities with magnitude and direction (e.g., velocity, force)
- Matrices: Rectangular arrays of numbers used to represent linear systems
- Linear Independence: A set of vectors where none can be expressed as a combination of others
- Dot Product: Measures the similarity between vectors
Matrix Operations 🔧
- Addition/Subtraction: Element-wise operations
- Multiplication: Combines matrices to transform data
- Determinants: Scalar value indicating matrix invertibility
- Transpose: Flips matrix dimensions
Applications 🌐
- Computer Graphics: 3D transformations via matrices
- Machine Learning: Weighted relationships in neural networks
- Physics: Solving systems of equations in mechanics
