Estimators
These are pipeline components that learn from vectorized input X & predict a target y.
In most cases estimators live at the end of the pipeline, but somtimes estimators can be used
as features within other models. The main types of estimators are:
| Type | Description |
|---|---|
| clusterers | predict or triage data into groups |
| classifiers | predict an enumerated value |
| regressors | predict a continuous value |
