Definition
In machine learning, optimization refers to the algorithms used to adjust model parameters to minimize a loss function, thereby improving model performance. Common methods include Gradient Descent and its variants like Adam or SGD. The goal is to navigate the parameter space efficiently to find global or local minima, ensuring the model generalizes well to unseen data by reducing the discrepancy between predicted and actual outputs.
