tf.keras.backend.in_top_k

TensorFlow 1 version View source on GitHub

Returns whether the targets are in the top k predictions.

Aliases:

  • tf.compat.v1.keras.backend.in_top_k
  • tf.compat.v2.keras.backend.in_top_k
tf.keras.backend.in_top_k(
    predictions,
    targets,
    k
)

Arguments:

  • predictions: A tensor of shape (batch_size, classes) and type float32.
  • targets: A 1D tensor of length batch_size and type int32 or int64.
  • k: An int, number of top elements to consider.

Returns:

A 1D tensor of length batch_size and type bool. output[i] is True if predictions[i, targets[i]] is within top-k values of predictions[i].
