verticapy.machine_learning.memmodel.cluster.KPrototypes.transform_sql#
- KPrototypes.transform_sql(X: list | ndarray) list[str] #
Transforms and returns the SQL distance to each cluster.
Parameters#
- X: ArrayLike
The names or values of the input predictors.
Returns#
- list
SQL code.
Examples#
Import the required module.
from verticapy.machine_learning.memmodel.cluster import KPrototypes
We will use the following attributes:
clusters = [ [0.5, 'high'], [1, 'low'], [100, 'high'], ] p = 2 gamma = 1.0 is_categorical = [0, 1]
Let’s create a model.
model_kp = KPrototypes(clusters, p, gamma, is_categorical)
Let’s use the following column names:
cnames = ['col1', 'col2']
Get the SQL code needed to deploy the model.
model_kp.transform_sql(cnames) Out[8]: ["POWER(POWER(col1 - 0.5, 2), 1 / 2) + 1.0 * (ABS((col2 = 'high')::int - 1))", "POWER(POWER(col1 - 1, 2), 1 / 2) + 1.0 * (ABS((col2 = 'low')::int - 1))", "POWER(POWER(col1 - 100, 2), 1 / 2) + 1.0 * (ABS((col2 = 'high')::int - 1))"]
