spark_metric_loss_score
def spark_metric_loss_score(metric_name: str, y_predict: psSeries, y_true: psSeries, sample_weight: psSeries = None, groups: psSeries = None) -> float
Compute the loss score of a metric for spark models.
Arguments:
metric_name
- str | the name of the metric.y_predict
- psSeries | the predicted values.y_true
- psSeries | the true values.sample_weight
- psSeries | the sample weights. Default: None.groups
- psSeries | the group of each row. Default: None.
Returns:
float | the loss score. A lower value indicates a better model.
