DeepLearnR tensorFlow Object system for R

Background

Enhance the R package to interface with DeepLearning Frameworks, specifically Google's TensorFlow. DeepLearning is a broad subject and this work would focus on a subset of features that add value to the R community for example a scalable implementation of CovNets & LSTM.

Related work

Currently there are no other packages. We are working on a package deepLearnR which implements initial features via rPython and skflow. The work on this GSOC proposal would be to enhance that package.

Expected impact

Interfaces to scalable deep learning frameworks is an essential capability to the R community. The bigger idea for the DeepLarnR package is to create a complete "wrapper" for TensorFlow probably starting with rPython eventually with rcpp as the c++ layer gets more richer interfaces

Mentors

Krishna Sankar ([@](mailto:ksankar42 {at} gmail {dot} com)) Billy Vreeland ([@](mailto:billyvreeland {at} gmail {dot} com))

Each project needs 2 mentors. Ideally one should be an expert R programmer with previous package development experience, and the other can be a domain expert in some other field or application area (optimization, bioinformatics, machine learning, data viz, etc).

Tests

Easy

1. Install deepLearnR package and run all the examples.
   • What are the results ?
   • What difficulties, if any, did you face installing the package ?
2. Change the data in the examples and show the results
   • You might have to tweak the learning rate and the epochs/steps
   • If you tweak the hyperparameters, show the results of the numbers you tried

Medium

1. Write an R function that creates a machine learning model and returns the results
   • You can choose your favorite model and a dataset
   • The function should have hyperparameters (appropriate to your model) that can be tweaked
2. Write a model in python using TensorFlow or skflow
   • On your own, don't use the examples already on the net or part of tutrials

Hard

1. Develop a small R package (say a new sumx function that adds two numbers and returns the result in a hex string)
2. Add all the required elements to pass R CMD check --as-cran
