NON-PARAMETRIC METHODS. K-NEAREST NEIGHBORS MODEL

Аннотация

One of the machine learning algorithms k-Nearest Neighbors algorithm is widely used for classification tasks in the construction of artificial intelligence programs. In the k-NN algorithm, when determining which class a new object belongs to, the distances from this object to all objects are measured, and if there are more objects belonging to which class among the nearest k selected objects, the new object is considered to belong to this class, which makes it makes it an intuitive and powerful tool for solving complex problems. In this article, a model for determining whether a patient is diagnosed with breast cancer or not is created using the k-NN algorithm. This problem is calculated using binary classification.
