WebbAll metrics in a compute group share the same metric state and are therefore only different in their compute step e.g. accuracy, precision and recall can all be computed from the true positives/negatives and false positives/negatives. By default, this argument is True which enables this feature. Webbtf.keras.metrics.Accuracy(name="accuracy", dtype=None) Calculates how often predictions equal labels. This metric creates two local variables, total and count that are used to compute the frequency with which y_pred matches y_true. This frequency is ultimately returned as binary accuracy: an idempotent operation that simply divides total by count.
