One of the most commonly used centroid-based clustering techniques is the k-means clustering algorithm. K-means assumes that the center of each cluster defines the cluster using a distance measure, mostly commonly Euclidean distance, to the centroid. To initialize the clustering, you provide a num...
Scalability: Many clustering algorithms can handle large datasets efficiently, making them suitable for big data applications. Disadvantages: Choice of Algorithm: The effectiveness of clustering depends on the choice of algorithm and similarity measure, which may not be straightforward. Determining the Numb...
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...

The process of clustering involves several steps. First, the dataset is prepared by selecting and pre-processing relevant features or attributes that capture the characteristics of the objects. Then, an appropriate clustering algorithm is applied to the dataset to group the objects based on their sim...
Clustering is an unsupervised learning method that organizes your data in groups with similar characteristics. Explore videos, examples, and documentation.

It’s important to note that analysis of clusters is not the job of a single algorithm. Rather, various algorithms usually undertake the broader task of analysis, each often being significantly different from others. Ideally, a clustering algorithm creates clusters where intra-cluster similarity is ...
K-means clustering is an unsupervised learning algorithm used for data clustering, which groups unlabeled data points into groups or clusters. It is one of the most popular clustering methods used in machine learning. Unlike supervised learning, the training data that this algorithm uses is unlabeled...
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. ...
