Классификация — задача supervised machine learning, в которой модель относит входы к дискретным категориям. Она включает бинарную классификацию с двумя классами, многоклассовую классификацию с более чем двумя классами и доменно-специфические формы, такие как классификация текста.
When the data is used to predict a category, supervised machine learning task is called classification. Binary classification refers to predicting only two categories (for example, classifying an image as a picture of either a 'cat' or a 'dog'). Multiclass classification refers to predicting multiple categories (for example, when classifying an image as a picture of a specific breed of dog).
In machine learning, a type of problem that seeks to place (classify) a data sample into a single category or "class." Often, classification problems are modeled to choose one category out of two. These are binary classification problems. Problems with more than two available categories are called "multiclass classification" problems.
