# klDiv

[common]\
fun [klDiv](klDiv.md)(input: [Tensor](../Tensor/index.md), target: [Tensor](../Tensor/index.md), reduction: [Reduction](../Reduction/index.md) = Reduction.MEAN, logTarget: [Boolean](https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-boolean/index.html) = false): [Tensor](../Tensor/index.md)

`klDiv(input: Tensor, target: Tensor, reduction: Reduction = Reduction.MEAN, logTarget: Boolean = false)`: the `kl_div` operator. Kullback–Leibler divergence loss. `input` is given in LOG space; `target` is probabilities unless `log_target` is set (then both are logs):
