KMeans

What is the formula to calculate the K-Means distance between cluster points?

sqrt((x2-x1)^2 + (y2-y1)^2)

What is the name of the formula used to calculate K-Means distance?

Euclidean distance

Calculate the K-Means for point 1 (2,10) with the centers A(2,10), B(5,8), and C(1,2). What is the closest center for point 1?

A

Calculate the K-Means for point 2 (2,5) with the centers A(2,10), B(5,8), and C(1,2). What is the closest center for point 2?

C

When do you stop calculating K-Means?

When there is no more change in the centroids.

What is the goal of the K-Means algorithm?

To find centroids that minimize the inertia, or within-cluster sum-of-squares criterion.

What formula is this for?

K-Means

What is the goal of the K-Means formula?

Minimize the distance between data points and centroid
