in_top_k(
    predictions,
    targets,
    k
)

Defined in tensorflow/contrib/keras/python/keras/backend.py.

Returns whether the targets are in the top k predictions.

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]`.
