Fundamentals of Data Mining

Data Science 101

Data mining is the process of discovering these patterns among the data and is therefore also known as Knowledge Discovery from Data (KDD). The models created using these algorithms could be evaluated against appropriate metrics to verify the model’s credibility. The choice of these metrics depends on the nature of the problem.

Due to its importance in both theory and applications, this algorithm is one of three algorithms awarded the Test of Time Award at the KDD conference in 2014. When we use the standard Euclidean distance metric, sometimes called the l 2 metric, our neighborhoods display this spherical shape. Why does this happen? Conclusion.
