Returns whether the targets are in the top k predictions.
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]. |
