-------------------------------------------
[~anoojp] Excellent! I've assigned it to you -- please let me know if you have
any questions. [~niketanpansare] would also be a great reference, as he
created the Caffe2DML project.
cc [~niketanpansare] I'm hoping that we can extend Caffe2DML with a
complementary Keras2DML frontend, reusing most of the existing infrastructure.
> Create Keras2DML: Keras frontend to SystemML

> Key: SYSTEMML-1819

> Project: SystemML
> Issue Type: New Feature

> This task covers the creation of a "Keras2DML" frontend for SystemML, built
> upon the [Caffe2DML |
> http://apache.github.io/systemml/beginners-guide-caffe2dml] infrastructure,
> that will allow users to define (and even train) models in Keras and then
> import them into SystemML for distributed training and prediction. As an
> initial set of thoughts, the input could be either (1) a Keras {{Model}}
> object, or (2) a saved Keras model hdf5 file, and the output of training
> could be either (1) a Keras {{Model}} object, (2) a saved Keras model hdf5
> file, or (3) a SystemML model.
> This would be a step towards a full-blown, official backend for Keras. The
> main goal here would be to allow users to be able to transparently make use
> of distributed training, without having to learn the details of SystemML.
> Initial steps:
> 1. Learn Keras
> 2. Learn Caffe2DML:
> [http://apache.github.io/systemml/beginners-guide-caffe2dml] Basically,
> Caffe2DML lets users import Caffe models (architecture and trained weights if
> available) into SystemML and train/predict on Spark with a scikit-learn
> compatible API without the user having to learn SystemML. The main benefit
> is distributed training without the user needing to think about it much. A
> bunch of the infrastructure is in place that I think Keras2DML would use.
> 3. Import a simple Keras model definition with a single Dense layer, and
> focus on hooking up the new Keras2DML class to the existing infrastructure.
> 4. Add reading of trained weights from Keras for the simple model, and hook
> up to existing infrastructure.
> 5. Expand out to increasingly complex models, aiming to be able to import all
> of the pretrained models from Keras, starting with VGG16 & ResNet50.
