Most online AI programs tend to group together machine learning, deep learning and generative AI, as they are all closely linked in real-world use. Machine learning usually comes first because it’s the foundation how systems actually learn from data. Then deep learning steps it up with neural networks that handle more complex patterns, and generative AI is what you see behind tools that create text, images, and similar outputs. In practice, these topics aren’t really taught in isolation, they’re blended through examples and hands-on work so it actually makes sense when you apply it. A good example is the online AI programs offered by H2K Infosys, where the training is structured to walk learners through all of these areas in a way that feels connected and practical rather than just theoretical.
