INTRODUCTION: Cluster analysis, also known as clustering, is a method of data mining that groups similar data points together. The goal of cluster analysis is to divide a dataset into groups (or clusters) such that the data points within each group are more similar to each other than to data points in other groups.

Data Mining Process. Data gathering: Data mining begins with the data gathering step, where relevant information is identified, collected, and organized for analysis. Data sources can include data warehouses, data lakes, or any other source that contains raw data in a structured or unstructured format.; Data preparation: In the second step, …

The data mining methods are inspected in terms of data generalization concept, where the data mining is performed by hiding the original information instead of trends and patterns. After data masking, the common data mining methods are employed without any modification. Two key factors, quality and scalability are specifically focused.

These two forms are as follows: Classification. Prediction. We use classification and prediction to extract a model, representing the data classes to predict future data trends. Classification predicts the categorical labels of data with the prediction models. This analysis provides us with the best understanding of the data at a large scale.

Data Mining Techniques. Data mining is highly effective, so long as it draws upon one or more of these techniques: 1. Tracking patterns. One of the most basic techniques in data mining is learning to recognize patterns in your data sets. This is usually a recognition of some aberration in your data happening at regular intervals, or an ebb …

To find a numerical output, prediction is used. The training dataset contains the inputs and numerical output values. According to the training dataset, the algorithm generates a model or predictor. When fresh data is provided, the model should find a numerical output. This approach, unlike classification, does not have a class label.
