Implement GradientDescentOptimizer

[migueldeicaza]

In Python Tensorflow, that is a highlevel operation that would be convenient to have in C#:

python/training/gradient_descent.py

[mdabros]

I have started to work on this with the goal of being able to finish the LinearRegression sample from the SampleTest project.

If anybody has already started to implement the GradientDecentOptimizer, or want to contribute, let me know. The branch I am working on can be found here:
https://github.com/mdabros/TensorFlowSharp/tree/gradient-descent-optimizer

@mdabros What is the status of the task?

@mdabros I think it would be okay if you make a WIP PR if you already has some results.

[mdabros]

Sadly I have not been able to spent much time on this, so the work is still very preliminary. Basically only the definition of some of the base types. Most of the work can be found here in the training namespace:
Training.

To be realistic I probably won't have time to continue this work until after December, so if anybody wants to contribute or take over, feel free to copy anything useful from my branch.

@mdabros I think the most sutable variant of you commit what you already have as WIP pull request (for keeping your work as yours). After that someone will continue.

[mdabros]

@alexpantyukhin Sure, if this is the preferred approach, I will submit a WIP pull request as soon as possible.

Just popping in to say I would like this too.

Yes, this would be great.
