Adaptive neural networks

Definition

Adaptive neural networks are a type of artificial neural network that can modify their structure and parameters in response to changes in the input data or environment. This adaptability allows them to learn from new information and improve their performance over time, making them especially useful in dynamic situations where conditions can vary widely.
