 Deep learning, a subset of machine learning, uses artificial neural networks with multiple hidden layers to model high-level abstractions. It learns from large datasets through backpropagation and gradient descent, enabling advancements in image and speech recognition, natural language processing, and autonomous systems. Deep learning's ability to automatically extract features from raw data sets it apart, making it a game-changer in technology.

wow, deep learning is wild! it's crazy how it can just pick up patterns from huge datasets. definitely a game-changer for tech! 🚀
