Cost Function
A Cost Function is a mathematical formula that measures the performance of a machine learning model on the entire dataset. It represents the average of the loss function values computed across all training examples.
Frequently Asked Questions
What is the difference between a loss function and a cost function?▼
A loss function measures error for a single training example. A cost function aggregates the errors across the entire dataset.
How does optimization relate to the cost function?▼
Optimization algorithms (like gradient descent) iteratively adjust parameter weights to locate the global minimum of the cost function.
