AI vs Machine Learning vs Deep Learning

The four nested layers — AI ⊃ ML ⊃ Deep Learning ⊃ Generative AI — explained with concrete decision criteria for picking the right one.

Interview

Explain self-attention. Why is it better than RNNs for sequence modeling?

Foundational LLM knowledge. If you can't explain attention, you can't reason about modern AI architectures.

Interview

When does classical ML with feature engineering beat deep learning?

Modern interviewers want signal that you don't reach for deep learning by default.

Interview

What's the difference between full fine-tuning, LoRA, and instruction tuning?

Modern AI work involves choosing the right fine-tuning approach. Tests current knowledge.
