What is Deep Learning?

Deep learning is a subset of machine learning that focuses on training artificial neural networks to mimic the way the human brain works. 

These neural networks are composed of interconnected layers of nodes (also known as artificial neurons), each responsible for processing and transforming data.

How Deep Learning is Different

Deep learning differs from traditional machine learning in several ways. 

Unlike traditional machine learning algorithms that rely on explicitly defined features, deep learning algorithms extract and learn features automatically from raw data. 

This means that deep learning models can handle more complex and unstructured data types, such as images, audio, and text, without extensive preprocessing.
