Clustering is an unsupervised machine learning algorithm that organizes and classifies different objects, data points, or observations into groups or clusters based on similarities or patterns.
The goal of the clustering algorithm is to find the optimal way to split the dataset into groups. Whatoptimalmeans depends on both the algorithm that's used and the dataset that's provided. Although this flower example can be simple for a human to group with only a few samples, more comp...

Clustering is an unsupervised learning method that organizes your data in groups with similar characteristics. Explore videos, examples, and documentation.
The K-medoids clustering algorithm offers an advantage for survey data analysis as it is suitable for both categorical and scalar data. This is because rather than measuring Euclidean distance between the medoid point and its neighbours, the algorithm can measure distance in multiple dimensions, repre...
There are in data mining a lot of ways in which clustering is conducted.1. Hierarchical MethodHierarchical Clustering is an unsupervised clustering algorithm that involves creating predominant clusters that have orders from top to bottom called Hierarchical cluster analysis or HCA. Hierarchical clustering...
What is a Dendrogram? A Dendrogram is a type of tree diagram showing hierarchical relationships between different sets of data. As already said a Dendrogram contains the memory of hierarchical clustering algorithm, so just by looking at the Dendrgram you can tell how the cluster is formed. ...
Clustering is one type of unsupervised learning where the goal is to partition the set of objects into groups called clusters. Faced to the difficulty to design a general purpose clustering algorithm and to choose a good, let alone perfect, set of criteria for clustering a data set, one ...

Hierarchical Clustering is a type of clustering algorithm which groups data points on the basis of similarity creating tree based cluster called dendrogram.
