# Optimization metrics

An optimization metric in machine learning refers to a measure of performance used to guide the training process of a model and evaluate its quality. The optimization metric is used to compare different models and determine the best one for a particular problem.

For example, in a binary classification problem, the optimization metric may be accuracy, which measures the proportion of correctly classified examples. In a regression problem, the optimization metric may be mean squared error, which measures the average difference between the predicted values and the actual values.

It's important to choose the right optimization metric for a particular problem and to consider other factors such as the cost of false positive and false negative predictions. The optimization metric should also be consistent with the goals of the model and the problem being solved.
