Usage
The following examples show how the step can be used in a recipe.Examples
Examples
The following parameters will discretize a column with values in the range [0, 1], producing a new categorical column with bins defined by the borders [0, 0.25), [0.25, 0.5), [0.5, 0.75) and [0.75, 1]. The bins will have labels “q1”, “q2”, “q3” and “q4” respectively.
Inputs & Outputs
The following are the inputs expected by the step and the outputs it produces. These are generally columns (ds.first_name), datasets (ds or ds[["first_name", "last_name"]]) or models (referenced
by name e.g. "churn-clf").
Inputs
Inputs
A numeric column to discretize.
Outputs
Outputs
A new categorical column with categories corresponding to discretized bins.
Configuration
The following parameters can be used to configure the behaviour of the step by including them in a json object as the last “input” to the step, i.e.step(..., {"param": "value", ...}) -> (output).
Parameters
Parameters
Quantiles.
Defines the quantiles or number of bins for discretizing the column.
Can be an array of cut points or a number indicating the number of bins.Values must be in the following range:
