tf.compat.v1.math.in_top_k(
predictions, targets, k, name=None
)
This outputs a batch_size
bool array, an entry out[i]
is true
if the
prediction for the target class is finite (not inf, -inf, or nan) and among
the top k
predictions among all predictions for example i
. Note that the
behavior of InTopK
differs from the TopK
op in its handling of ties; if
multiple classes have the same prediction value and straddle the top-k
boundary, all of those classes are considered to be in the top k
.
More formally, let
be the predictions for all classes for example i
,
be the target class for example i
,
be the output for example i
,
