## Keras Model Import: Supported Features

Little-known fact: Deeplearning4j's creator, Skymind, has two of the top
five [Keras contributors](https://github.com/keras-team/keras/graphs/contributors)
on our team, making it the largest contributor to Keras after Keras creator Francois
Chollet, who's at Google.

While not every concept in DL4J has an equivalent in Keras and vice versa, many of the
key concepts can be matched. Importing keras models into DL4J is done in
our [deeplearning4j-modelimport](https://github.com/deeplearning4j/deeplearning4j/tree/master/deeplearning4j/deeplearning4j-modelimport/src/main/java/org/deeplearning4j/nn/modelimport/keras)
module. Below is a comprehensive list of currently supported features.

## <a name="layers">Layers</a>
Mapping keras to DL4J layers is done in the [layers](https://github.com/deeplearning4j/deeplearning4j/tree/master/deeplearning4j/deeplearning4j-modelimport/src/main/java/org/deeplearning4j/nn/modelimport/keras/layers) sub-module of model import. The structure of this project loosely reflects the structure of Keras.
