luokitteluraja
Luokitteluraja, often translated as classification threshold or cutoff, is a critical concept in statistical classification and machine learning. It represents the value at which a classifier decides whether an instance belongs to one class or another. For binary classification problems, where there are only two possible outcomes (e.g., positive or negative, spam or not spam), a classification model typically outputs a probability or a score indicating the likelihood of an instance belonging to the positive class. The luokitteluraja is then used to convert this continuous score into a discrete class label.
If the model's output score is above the luokitteluraja, the instance is assigned to the positive class.
