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]`.
