What is the K in K-Nearest Neighbors?Answer areaThe number of classesThe number of nearest neighbors to consider for classificationThe number of features in the datasetThe number of layers in the model

When applying k-Nearest Neighbors (KNN) for classification, what is the role of the "k" parameter?a.It specifies the number of dimensions in the dataset.b.It determines the learning rate in the algorithm.c.It defines the number of clusters.d.It sets the number of nearest neighbors to consider for classification.

What should be the number of neighbors for the K-nearest neighbor regressor?

In K Nearest Neighbours classification, which of the following statements about K and N (the number of training samples) is/are true?Group of answer choicesK impacts both the accuracy and the computational complexity of the KNN algorithm.K and N should be linearly related, i.e. K/N should be a pre-determined constant.The time taken to perform the classification task increases with N.K should be odd to avoid ties.
