k_in_top_k
Returns whether the targets are in the top k predictions.
Description
Returns whether the targets are in the top k predictions.
Usage
k_in_top_k(predictions, targets, k) Arguments
| Arguments | Description |
|---|---|
| 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. |

Keras Backend
This function is part of a set of Keras backend functions that enable lower level access to the core operations of the backend tensor engine (e.g. TensorFlow, CNTK, Theano, etc.). You can see a list of all available backend functions here: https://keras.rstudio.com/articles/backend.html#backend-functions.
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]].
