AI vs ML vs Deep Learning — Tutorial

Three nested circles

Artificial Intelligence is the broadest field — any technique that enables a machine to mimic intelligent behaviour. Machine Learning is a subset: systems that learn from data rather than following hand-written rules. Deep Learning is a subset of ML that uses neural networks with many layers to learn hierarchical representations.

The circles nest: all DL is ML, and all ML is AI. When a journalist says "AI," they usually mean ML. When a researcher says "deep learning," they mean a specific family of neural architectures.

What actually separates them

Traditional AI (rules-based): a programmer encodes every decision — "if email contains 'winner' → spam." Brittle; requires expert knowledge for every case.

Machine Learning: the algorithm finds the rules from labeled examples. You supply (email, spam/not-spam) pairs; the model discovers the patterns. Requires good features (word counts, sender domain…).

Deep Learning: the neural network learns both the features AND the decision boundary from raw data (pixels, tokens). More data-hungry and compute-intensive, but often surpasses hand-crafted features on unstructured inputs like images, audio, and text.

Practical rule of thumb

Use classical ML (sklearn) when: data is tabular, you have <100k rows, you need interpretability, or compute is limited.

Use deep learning when: data is unstructured (images, audio, text), you have millions of examples, and a GPU is available.

Use rules/heuristics when: the problem is fully enumerable, you need guaranteed behavior, or you have almost no data.
