Methods
__construct
Constructor.
| Parameters | |
|---|---|
| Name | Description |
data |
array
Optional. Data for populating the Message object. |
↳ confidence_threshold |
float
Output only. Metrics are computed with an assumption that the model never returns predictions with score lower than this value. |
↳ position_threshold |
int
Output only. Metrics are computed with an assumption that the model always returns at most this many predictions (ordered by their score, descendingly), but they all still need to meet the confidence_threshold. |
↳ recall |
float
Output only. Recall (True Positive Rate) for the given confidence threshold. |
↳ precision |
float
Output only. Precision for the given confidence threshold. |
↳ false_positive_rate |
float
Output only. False Positive Rate for the given confidence threshold. |
↳ f1_score |
float
Output only. The harmonic mean of recall and precision. |
↳ recall_at1 |
float
Output only. The Recall (True Positive Rate) when only considering the label that has the highest prediction score and not below the confidence threshold for each example. |
↳ precision_at1 |
float
Output only. The precision when only considering the label that has the highest prediction score and not below the confidence threshold for each example. |
↳ false_positive_rate_at1 |
float
Output only. The False Positive Rate when only considering the label that has the highest prediction score and not below the confidence threshold for each example. |
↳ f1_score_at1 |
float
Output only. The harmonic mean of recall_at1 and precision_at1. |
↳ true_positive_count |
int|string
Output only. The number of model created labels that match a ground truth label. |
↳ false_positive_count |
int|string
Output only. The number of model created labels that do not match a ground truth label. |
↳ false_negative_count |
int|string
Output only. The number of ground truth labels that are not matched by a model created label. |
↳ true_negative_count |
int|string
Output only. The number of labels that were not created by the model, but if they would, they would not match a ground truth label. |
