What is supervised data mining techniques?

Supervised data mining techniques are appropriate when you have a specific target value you'd like to predict about your data . ... You then apply that model to data for which that target value is currently unknown. The algorithm identifies the “new” data points that match the model of each target value.

Is an unsupervised data mining technique?

Unlike supervised technique, unsupervised data mining does not have a predetermined objective function, nor does it predict a target value. Unsupervised techniques are those where there is no outcome variable to predict or classify . Hence, there is no learning from cases where such an outcome variable is known.

What are supervised and unsupervised learning?

In a supervised learning model, the algorithm learns on a labeled dataset, providing an answer key that the algorithm can use to evaluate its accuracy on training data. An unsupervised model, in contrast, provides unlabeled data that the algorithm tries to make sense of by extracting features and patterns on its own.
