Basic Math Concepts – Ridge Regression
1. Algebra
- What We Need:
- Solving linear equations (e.g., 2x+3=112x + 3 = 112x+3=11)
- Understanding variables and coefficients
- Rearranging formulas
- Real-Life Analogy:
- Figuring out how many apples we can buy if 1 apple costs ₹5 and we have ₹25.
2. Coordinate Geometry
- What We Need:
- Understanding how to plot points on an X-Y graph
- Concept of a line: y=mx+by = mx + by=mx+b
- Slope (m), intercept (b), and how they affect the line
- Real-Life Analogy:
- Mapping how house price increases as size increases on a graph.
3. Matrix Basics
- What We Need:
- What is a matrix and vector
- Matrix addition and multiplication
- Transpose of a matrix
- Identity matrix (like multiplying by 1)
- Inverse matrix (like division for matrices)
- Real-Life Analogy:
- Think of matrices as Excel tables — rows and columns of numbers being operated together.
4. Statistics
- What We Need:
- Mean (average)
- Variance and standard deviation
- Correlation between variables
- Real-Life Analogy:
- Understanding how crime rate and house price may move together.
5. Linear Regression
-
What We Need:
- Understanding of how regression fits a line through data
- Concept of error/residual (difference between prediction and actual)
- Overfitting vs underfitting
-
Real-Life Analogy:
- Trying to guess a student’s marks based on their study time, and adjusting our guess if we’re too far off.
6. Loss Functions
-
What We Need:
- Mean Squared Error (MSE) and why we square the differences
- The goal of minimizing error
-
Real-Life Analogy:
- Like minimizing the distance between our guess and the correct answer in a dart game.
7. Regularization (Conceptual Only)
-
What We Need:
- Why we want to control the size of coefficients
- The idea of penalizing complexity
-
Real-Life Analogy:
- Telling our AI assistant: “Don’t give wild guesses just to be right — stay reasonable.”
