K-Means Cluster - Python Data Function for Spotfire® 1.0.0

Overview

This Python data function helps in grouping data into two or more groups based on the properties of the data, and more exactly based on certain patterns which are more or less obvious in the data. The goal is to find those patterns in the data that help us be sure that, given a certain item in our dataset, we will be able to correctly place the item in a correct groups represented by K, so that it is similar to other items in that group, but different from items in other groups.

The ideal result for this data function is that two items in the same group are as similar to each other, while two items from different groups are as different as possible.

Also available as a Statistica data function.

Configuring the data function

Each data function may require inputs from the Spotfire analysis and will return outputs to the Spotfire analysis. For each data function, these need to be configured once the data function is registered. To learn about how to configure data functions in Spotfire please view this video:
