Example text

Target_names array(['setosa', 'versicolour', 'virginica'], dtype='|S10') Although we’re working with a simple dataset, the concepts that you can learn here are universal among machine-learning algorithms. You’ll see later in this chapter how you can draw on machine learning to extract the structure of the data and how different techniques can be adopted to achieve this. To illustrate the concept of structure, let’s try some thought experiments with the Iris dataset. It may be that all Virginicas are much bigger than the other flowers, such that the lengths and widths of the sepals and petals have significantly higher values.

1, it’s equivalent to understanding that x increases with y regardless of the class of data. The method we’ll cover is known as principal component analysis (PCA). Used on its own, this algorithm uncovers the principal directions of variance in your data—helping you understand which of your features are important and which are not. It can also be used to map your data into a smaller feature space—that is, one with fewer data features—without losing much of the information it captures. Consequently, it can be used as a preprocessing step to your clustering algorithms (or any other intelligent algorithm).

The leftmost points might be considered to be clustered in the range 0–6, whereas the points to the right might be clustered in the range 9–16. We don’t necessarily know that this is a good clustering, but if we were to use our judgment, we might hazard a guess that they’re significantly different enough to be considered different groups of points. This is essentially what all clustering algorithms seek to do: to create groups of data points that we may consider to be clusters of points or structure in the data.
