🔍 What is Deep Learning Foundation?

Deep Learning Foundation refers to the fundamental concepts, mathematical principles, and technical skills required to understand and work with deep learning, a subfield of machine learning that uses neural networks with many layers to model complex patterns in data.

It is the base layer of knowledge you need before building advanced models like GPT, image classifiers, self-driving systems, or AI in trading.

🧠 What is Deep Learning?

Deep learning uses artificial neural networks, especially deep neural networks (with many layers), to learn from large amounts of data.

It's inspired by the way the human brain processes information but works using math, algorithms, and data.

📚 Key Components of the Deep Learning FoundationMathematics

Linear Algebra: Vectors, matrices, matrix multiplication (used in layers).

Calculus: Derivatives, gradients (used in optimization).

Probability & Statistics: Helps in data distribution, loss functions, regularization.

Programming Skills

Python: The most popular language for deep learning.

Familiarity with NumPy, Pandas, Matplotlib, etc.
