Machine learning is a broad field with many different approaches. One of the most powerful of these is deep learning , which takes inspiration directly from the human brain. Let’s break down what this means, and how it connects to generative AI —the technology behind tools like ChatGPT, image generators, and more. Deep Learning: The Next Step in Machine Learning Machine Learning (ML) : Covers many techniques that let computers learn from data. Deep Learning : A specialized branch of ML that uses artificial neural networks (ANNs) to learn more complex patterns. Just like your brain, ANNs are made of interconnected neurons (nodes). These neurons process data, make predictions, and when stacked in multiple layers , they become capable of recognizing very complex patterns—far beyond what traditional ML models can do. Supervised, Unsupervised, and Semi-Supervised Neural networks can work with: Supervised data (labeled) Unsupervised data (unlabeled) Semi-supervis...

When we talk about machine learning (ML), two major categories often come up: supervised and unsupervised learning. Understanding these two approaches is essential, because they form the foundation for more advanced topics—like deep learning and generative AI. The Key Difference: Labels  Supervised Learning : Works with labeled data —that means the dataset already comes with tags, like a name, category, or number. Unsupervised Learning : Works with unlabeled data —raw information with no predefined tags. Think of labels as answers to a question. Supervised models are trained with those answers, while unsupervised models try to uncover patterns without them. A Real-World Supervised Example Imagine you own a pizza restaurant. 🍕 You have historical data about: The total bill amount Whether the order was pickup or delivery The tip amount With supervised learning, your model studies this past data to predict future tips . For example, given a new bill tot...
