Deep learning is a machine-learning approach built from neural networks with multiple hidden layers. Each layer transforms inputs through connected nodes, while training adjusts connection weights and bias terms to improve a defined objective. section 1.1
Its strength comes from learning complex patterns in very large datasets. This makes it useful for natural language processing, while its complexity depends partly on the number of learned parameters. section 1.1
Deep learning systems involve:
- Data, such as text for natural language tasks. section 1.1
- An objective function that defines what the model should improve. section 1.1
- Training that iteratively updates weights and biases. section 1.1
