AutoClustering¶
In [ ]:
class AutoClustering(name: str,
n_cluster: int = None,
init: str = "kmeanspp",
max_iter: int = 300,
tol: float = 1e-4,
preprocess_data: bool = True,
preprocess_dict: dict = {"identify_ts": False, "normalize_min_cat": 0,
"outliers_threshold": 3.0, "na_method": "drop",},
print_info: bool = True,)
Automatically creates k different groups with which to generalize the data.
Parameters¶
| Name | Type | Optional | Description |
|---|---|---|---|
name | str | ❌ | Name of the model. |
n_cluster | int | ✓ | Number of clusters. If empty, an optimal number of clusters will be determined using multiple k-means models. |
init | str / list | ✓ | The method for finding the initial cluster centers.
|
max_iter | int | ✓ | The maximum number of iterations for the algorithm. |
tol | float | ✓ | Determines whether the algorithm has converged. The algorithm is considered converged after no center has moved more than a distance of 'tol' from the previous iteration. |
preprocess_data | bool | ✓ | If True, the data will be preprocessed. |
preprocess_dict | dict | ✓ | Dictionary to pass to the AutoDataPrep class in order to preprocess the data before the clustering. |
print_info | bool | ✓ | If True, prints the model information at each step. |
Attributes¶
| Name | Type | Description |
|---|---|---|
preprocess_ | object | Model used to preprocess the data. |
model_ | object | Final model used for the clustering. |
Main Methods¶
| Name | Description |
|---|---|
| Trains the model. |
AutoClustering also inherits the vModel methods.
Example¶
In [1]:
from verticapy.learn.delphi import AutoClustering
model = AutoClustering("titanic_autoClustering")
model.fit("public.titanic",)
