# Regularizers

All \[Keras regularizers] are supported by DL4J model import:

* &#x20;l1
* &#x20;l2
* &#x20;l1\_l2

Mapping of regularizers can be found in [KerasRegularizerUtils](https://github.com/eclipse/deeplearning4j/blob/master/deeplearning4j/deeplearning4j-modelimport/src/main/java/org/deeplearning4j/nn/modelimport/keras/utils/KerasRegularizerUtils.java).
