Answers
Data Mining: Data mining in general terms means mining or digging deep into data which is in different forms to gain patterns, and to gain knowledge on that pattern. In the process of data mining, large data sets are first sorted, then patterns are identified and relationships are established to perform data analysis and solve problems.
Classification: It is a Data analysis task, . the process of finding a model that describes and distinguishes data classes and concepts. Classification is the problem of identifying to which of a set of categories (sub populations), a new observation belongs to, on the basis of a training set of data containing observations and whose categories membership is known.
Example: Before starting any Project, we need to check it’s feasibility. In this case, a classifier is required to predict class labels such as ‘Safe’ and ‘Risky’ for adopting the Project and to further approve it. It is a two step process such as
