tf.compat.v1.keras.metrics.sparse_top_k_categorical_accuracy
tf.keras.metrics.sparse_top_k_categorical_accuracy(
y_true, y_pred, k=5
)
Standalone usage:
y_true = [2, 1] y_pred = [[0.1, 0.9, 0.8], [0.05, 0.95, 0]] m = tf.keras.metrics.sparse_top_k_categorical_accuracy( ... y_true, y_pred, k=3) assert m.shape == (2,) m.numpy() array([1., 1.], dtype=float32)
