WebSep 7, 2024 · Since the true labels of the synthetic dataset are known, we use the Rand index adjusted for chance (ARI) [27, 34] to evaluate our clustering results and the clustering accuracy (ACC) . The Rand index is a measure of similarity between two data clusterings and can be computed as follows : Definition 9. Rand index 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 …
