class MinWeightedF1Score#

Bases: BaseAccuracy

Subclass of BaseAccuracy that implements the minimum weighted f1 score.

alias_name#

The name for config.

Type:

str

transform(y_true, params) → Any#

Creates accuracy test results.

__init__()#

Methods

__init__()

async_run(sample_list, y_true, y_pred, **kwargs)

class TestConfig#

Bases: dict

clear() → None.  Remove all items from D.#
copy() → a shallow copy of D#
fromkeys(value=None, /)#

Create a new dictionary with keys from iterable and values set to value.

get(key, default=None, /)#

Return the value for key if key is in the dictionary, else default.

items() → a set-like object providing a view on D's items#
keys() → a set-like object providing a view on D's keys#
pop(k[, d]) → v, remove specified key and return the corresponding value.#

If the key is not found, return the default if given; otherwise, raise a KeyError.

popitem()#

Remove and return a (key, value) pair as a 2-tuple.

Pairs are returned in LIFO (last-in, first-out) order. Raises KeyError if the dict is empty.

setdefault(key, default=None, /)#

Insert key with a value of default if key is not in the dictionary.

Return the value for key if key is in the dictionary, else default.

update([E, ]**F) → None.  Update D from dict/iterable E and F.#

If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]

values() → an object providing a view on D's values#
async classmethod async_run(sample_list: List[MinScoreSample], y_true: List[Any], y_pred: List[Any], **kwargs)#

Creates a task to run the accuracy measure.

Parameters:

  • sample_list (List[MinScoreSample]) – List of samples to be transformed.

  • y_true (List[Any]) – True values

  • y_pred (List[Any]) – Predicted values

async run(y_true: List[Any], y_pred: List[Any], **kwargs)#

Computes the minimum F1 score for the given data.

Parameters:

  • sample_list (List[MinScoreSample]) – List of samples to be transformed.

  • y_true (List[Any]) – True values

  • y_pred (List[Any]) – Predicted values

classmethod transform(test: str, y_true: List[Any], params: Dict) → List[MinScoreSample]#

Computes the minimum weighted F1 score for the given data.

Parameters:

  • y_true (List[Any]) – True values

  • params (Dict) – parameters for tests configuration

Returns:

The transformed data based on the minimum F1 score.

Return type:

List[MinScoreSample]
