Tkinter 8.5 reference: a GUI for Python The k-means clustering method is an unsupervised machine learning technique used to identify clusters of data objects in a dataset. There are many different types of clustering methods, but k-means is one of the oldest and most approachable.These traits make implementing k-means clustering in Python reasonably straightforward, even for novice programmers and data scientists. Depends on the algorithm you are going to feed these features to. This transformer should be used to encode target values, i.e. It also really depends on your dataset. For example, when we work with datasets for salary estimation based on different sets of features, we often see job title being entered in words, for example: Manager, Director, Vice-President, President, and so on. This is not what you want to have right? And how sensitive it is to the ranges and distributions of numerical features. ActiveState Code – Popular Python recipes.
