Why Developers Need To Know About Matrix Transpose

You've seen the 'T' in machine learning equations, but what does it actually do? In this video, we decode the matrix transpose, a simple operation that is absolutely fundamental to training ML models like Linear Regression and even deep neural networks. We'll cover the what, the how (in NumPy), and most importantly, the why.

This is a core lesson in our "Foundations" series, designed for engineers and practitioners who need to understand the math that powers modern AI and Data Science.

🎓 IN THIS VIDEO, YOU WILL LEARN:
The intuitive, visual explanation of a Matrix Transpose.
How to perform a transpose in one character of code using Python and NumPy.
Role #1: How the transpose is used to align matrix dimensions for multiplication.
Role #2: How the transpose is the key to unlocking model training formulas like the Normal Equation for Linear Regression.
