Material for ODL workshop Dec 2017

odlworkshop's Issues

Use rebin package to do binning

https://pypi.python.org/pypi/rebin/1.0.1

Very nice interface

Move repo to odlgroup

Since this counts as "official content" I think it should be on @odlgroup's list of repos.

More broken links

Similar to #27 , there are:

• two broken "first notebook" links in part1_using_a_different_solver.ipynb
• a broken "above" link in part1_tv_denoising.ipynb

Structure the material

We need to move some stuff into folders and add a readme that explains where to start and what all files do.

Add learning exercises

We need to add exercises to the deep learning parts.

handout version of lectures

Minor nitpick: it would be a bit easier to read the presentations below if they were recompiled (or have two versions) with "handout" - i.e., using \documentclass[handout]{beamer}

https://github.com/odlgroup/odlworkshop/blob/master/presentations/ODL_intro_HK.pdf

https://github.com/odlgroup/odlworkshop/blob/master/presentations/introduction_JA.pdf

https://github.com/odlgroup/odlworkshop/blob/master/presentations/machine_learning_intro_JA.pdf

Broken links to notebooks from maxiv-course-oct-17

The first sentence in "part1_exercises.ipynb" contains two links ("first" and "two"). It looks like both are broken. Probably, they were related to these notebooks, but they are not present in this repo.

nomkl & pyfftw on Windows

conda install nomkl and conda install -c conda-forge pyfftw currently fail for me on Windows with PackageNotFoundError. But at least some stuff from the "part1" seem to work. Are they optional actually?

Remove _ syntax

It seems we have

_ = x_true.show('True image')

in quite a few places. I personally prefer

x_true.show('True image');

which does the same thing

Discussion: Should all the notebooks be pre-run online?

I vote yes.

Add more dependencies

We should add

• pywavelets
• scikit-learn
• scikit-image
• pytorch

Installation instructions - trouble

When following the official documentation at

https://github.com/adler-j/odlworkshop/blob/master/code/part0_install.ipynb

(on radon) I get the following error when testing tensorflow (the install proceeded ok.) Possibly radon is out of wack, but no luck with gelfand either (it's out of disk space.)

Make alternative notebooks using pyTorch

Best odl version?

• README.md says "Use the conda variant if possible" (which is 0.5.2 for me on Windows)
• code/part0_install.ipynb says pip install https://github.com/odlgroup/odl/archive/master.zip (which is 0.6.1dev0)
