Computes how often integer targets are in the top K predictions.
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)
