What is deep learning?

Definition

Deep learning is a subset of machine learning. It lets you use specialized algorithms to automatically obtain new insights and interpretations from data.

The gist of deep learning

Layered, hierarchical learning

Distinct algorithms per layer

Error identification and correction

Deep learning vs. plain machine learning

• A plain machine-learning model tries to learn all features in sample data at once. A deep-learning model learns progressively, using layers of algorithms.
• Plain machine learning requires manual intervention for feature selection and error correction. Deep learning handles these tasks automatically.

A few applications of deep learning

• Speech recognition
• Image classification
• Language translation
• Text-to-speech conversion
