```python
model.train(X_batch, Y_batch)

Building a network of LSTMs, a deep CNN, a word2vec embedder or any other model is just as fast. The ideas behind deep learning are simple, so why should their implementation be painful?

- Keep a pragmatic mindset and avoid bloat. Only add to the source if that is the only path forward.
- New features should be documented. Make sure you update the documentation along with your Pull Request.
- The documentation for every new feature should include a usage example in the form of a code snippet.
- All changes should be tested. A formal test process will be introduced very soon.
- All changes should be tested. Make sure any new feature you add has a corresponding unit test.
- Even if you don't contribute to the Keras source code, if you have an application of Keras that is concise and powerful, please consider adding it to our collection of [examples](https://github.com/fchollet/keras/tree/master/examples).

Keras (κέρας) means _horn_ in Greek. It is a reference to a literary image from ancient Greek and Latin literature, first found in the _Odyssey_, where dream spirits (_Oneiroi_, singular _Oneiros_) are divided between those who deceive men with false visions, who arrive to Earth through a gate of ivory, and those who announce a future that will come to pass, who arrive through a gate of horn. It's a play on the words κέρας (horn) / κραίνω (fulfill), and ἐλέφας (ivory) / ἐλεφαίρομαι (deceive).
Keras was developed as part of the research effort of project ONEIROS (Open-ended Neuro-Electronic Intelligent Robot Operating System).

> _"Oneiroi are beyond our unravelling --who can be sure what tale they tell? Not all that men look for comes to pass. Two gates there are that give passage to fleeting Oneiroi; one is made of horn, one of ivory. The Oneiroi that pass through sawn ivory are deceitful, bearing a message that will not be fulfilled; those that come out through polished horn have truth behind them, to be accomplished for men who see them."_

Merge the output of a list of models into a single tensor, following one of two modes: `sum` or `concat`.
Merge the output of a list of layers (or containers) into a single tensor, following one of two modes: `sum` or `concat`.
- __Arguments__:
- __models__: List of `Sequential` models.
- __mode__: String, one of `{'sum', 'concat'}`. `sum` will simply sum the outputs of the models (therefore all models should have an output with the same shape). `concat` will concatenate the outputs along the last dimension (therefore all models should have an output that only differ along the last dimension).
- __layers__: List of layers or [containers](/layers/containers/).
