VideoActionMetrics

The Evaluation metrics given a specific precisionWindowLength.

Fields
confidenceMetrics[] object (ConfidenceMetrics)

Metrics for each label-match confidenceThreshold from 0.05,0.10,...,0.95,0.96,0.97,0.98,0.99.

precisionWindowLength string (Duration format)

This VideoActionMetrics is calculated based on this prediction window length. If the predicted action's timestamp is inside the time window whose center is the ground truth action's timestamp with this specific length, the prediction result is treated as a true positive.

A duration in seconds with up to nine fractional digits, ending with 's'. Example: "3.5s".

meanAveragePrecision number

The mean average precision.

ConfidenceMetrics

Metrics for a single confidence threshold.

Fields
confidenceThreshold number

Output only. The confidence threshold value used to compute the metrics.

recall number

Output only. Recall for the given confidence threshold.

precision number

Output only. Precision for the given confidence threshold.

f1Score number

Output only. The harmonic mean of recall and precision.
