It analyzes data (age, email history) to estimate the chance (0-1) of an event. A sigmoid function turns this into a probability. We can then set a threshold (e.g. 0.5) to classify (open/not open). K-means is a centroid-based algorithm or a distance-based algorithm, where we calculate the distances to assign a point to a cluster. In K-Means, each cluster is associated with a centroid. The main objective of the K-Means algorithm is to minimize the sum of distances between the points and their respective cluster centroid.Analytics Vidhya is the leading community of Analytics, Data Science and AI professionals.
