RepeatedStratifiedKFold

Repeated Stratified K-Fold cross validator.

Repeats Stratified K-Fold n times with different randomization in each repetition.

Constructors

constructor()

Signature

new RepeatedStratifiedKFold(opts?: object): RepeatedStratifiedKFold;

Parameters

Name	Type	Description
`opts?`	`object`	-
`opts.n_repeats?`	`number`	Number of times cross-validator needs to be repeated. `Default Value` `10`
`opts.n_splits?`	`number`	Number of folds. Must be at least 2. `Default Value` `5`
`opts.random_state?`	`number`	Controls the generation of the random states for each repetition. Pass an int for reproducible output across multiple function calls. See Glossary.

Returns

RepeatedStratifiedKFold

Defined in: generated/model_selection/RepeatedStratifiedKFold.ts:25 (opens in a new tab)

Methods

dispose()

Disposes of the underlying Python resources.

Once dispose() is called, the instance is no longer usable.

Signature

dispose(): Promise<void>;

Returns

Promise<void>

Defined in: generated/model_selection/RepeatedStratifiedKFold.ts:108 (opens in a new tab)

get_metadata_routing()

Get metadata routing of this object.

Please check User Guide on how the routing mechanism works.

Signature

get_metadata_routing(opts: object): Promise<any>;

Parameters

Name	Type	Description
`opts`	`object`	-
`opts.routing?`	`any`	A `MetadataRequest` encapsulating routing information.

Returns

Promise<any>

Defined in: generated/model_selection/RepeatedStratifiedKFold.ts:127 (opens in a new tab)

get_n_splits()

Returns the number of splitting iterations in the cross-validator

Signature

get_n_splits(opts: object): Promise<number>;

Parameters

Name	Type	Description
`opts`	`object`	-
`opts.X?`	`any`	Always ignored, exists for compatibility. `np.zeros(n\_samples)` may be used as a placeholder.
`opts.groups?`	`ArrayLike`	Group labels for the samples used while splitting the dataset into train/test set.
`opts.y?`	`any`	Always ignored, exists for compatibility. `np.zeros(n\_samples)` may be used as a placeholder.

Returns

Promise<number>

Defined in: generated/model_selection/RepeatedStratifiedKFold.ts:165 (opens in a new tab)

init()

Initializes the underlying Python resources.

This instance is not usable until the Promise returned by init() resolves.

Signature

init(py: PythonBridge): Promise<void>;

Parameters

Name	Type
`py`	`PythonBridge`

Returns

Promise<void>

Defined in: generated/model_selection/RepeatedStratifiedKFold.ts:62 (opens in a new tab)

split()

Generates indices to split data into training and test set.

Signature

split(opts: object): Promise<ArrayLike>;

Parameters

Name	Type	Description
`opts`	`object`	-
`opts.X?`	`ArrayLike`[]	Training data, where `n\_samples` is the number of samples and `n\_features` is the number of features.
`opts.groups?`	`ArrayLike`	Group labels for the samples used while splitting the dataset into train/test set.
`opts.y?`	`ArrayLike`	The target variable for supervised learning problems.
