WebContribute to Sorooshi/AE-VAE-Clustering development by creating an account on GitHub. Webtf.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.
