📘 Background Theory
🧠 What Is Machine Learning?
Machine Learning is a subset of Artificial Intelligence that enables systems to learn patterns from data and make decisions without being explicitly programmed for every scenario. Instead of writing rules manually, engineers train models using data.
There are three main categories of ML:
-
Supervised Learning – Models learn from labeled data
-
Unsupervised Learning – Models find patterns in unlabeled data
-
Reinforcement Learning – Models learn by interacting with an environment
TensorFlow supports all these paradigms, making it a versatile framework.
🔢 Why Mathematics Matters
Behind TensorFlow lies strong mathematical foundations:
-
Linear Algebra – Vectors, matrices, tensors
-
Calculus – Gradients and backpropagation
-
Probability & Statistics – Loss functions, uncertainty
Don’t worry—TensorFlow abstracts most of the math, but understanding the basics helps engineers debug, optimize, and innovate.
