I want to work on bike-sharing data. I want to classify the group of bike users, based on the area they used most to ride bikes. How can group them based on proximity?

There are many unsupervised learning algorithms. **K-means clustering** is most commonly used for grouping of data. In k-means grouping is done based on the similarity of features. It is the simplest unsupervised learning algorithm that solves the clustering problem.

In the bike-sharing dataset, grouping can be done based on ‘proximity of area’ or ‘age’ or ‘gender’ of the bike users. You will find more about this once you implement the k-means algorithm.

You can find more about this algorithm here.

It works by dividing a large set of points (vectors) into groups having approximately the same number of points closest to them. Each group is represented by its centroid point, as in k-means and some other clustering algorithms.

**Some other fields related to clustering are**

**Marketing****Biology****Libraries****Insurance****City Planning****Earthquake studies**

**And many more…**

There are many other applications of clustering, depends on the dataset, you want to work on.
