Deep learning is a subset of machine learning that structures algorithms in layers to create an "artificial neural network" that can learn and make intelligent decisions on its own.
Key Concepts
- Neural Networks: These are models inspired by the human brain, where each neuron represents a feature and the connections between neurons represent the relationships between features.
- Layers: Deep learning models consist of multiple layers, including input, hidden, and output layers. Each layer processes the input data and passes it to the next layer.
- Activation Functions: These functions help determine whether a neuron should be activated or not based on its input.
- Backpropagation: This is a technique used to train deep learning models by adjusting the weights and biases of the neurons based on the error rate.
Applications
- Image Recognition: Deep learning models can be used to recognize objects in images, such as identifying cats in photos.
- Natural Language Processing (NLP): These models can understand and generate human language, making them useful for tasks like machine translation and sentiment analysis.
- Recommender Systems: Deep learning models can analyze user behavior and preferences to recommend products or content.
