# Deep learning

Concept · [Building with AI](https://ecosystem.samcarlton.com/ai)

Also called: deep neural networks, DL, deep net

[Machine learning](https://ecosystem.samcarlton.com/terms/ai) using [neural networks](https://ecosystem.samcarlton.com/neural-network) with many layers. It is the approach behind today's language, image and speech models.

**For example:** [Speech-to-text](https://ecosystem.samcarlton.com/speech-to-text) got much more accurate once it switched to deep learning.
