Returns whether the <code>targets</code> are in the top <code>k</code> <code>predictions</code>.

Returns whether the targets are in the top k predictions.

k_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.

Value

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]].
