What is Deep Learning?
Definition
Deep Learning is a subset of machine learning using artificial neural networks with multiple layers ("deep" networks) to learn hierarchical representations of data. These multiple layers progressively extract higher-level features from raw input, enabling the model to learn complex patterns without manual feature engineering.
Key Architectures
- CNNs (Convolutional Neural Networks): Image recognition, object detection
- RNNs/LSTMs: Sequence data, time series, text
- Transformers: NLP, language models, attention mechanisms
- GANs: Generative models, image synthesis
