Note that, if any student is interested, the Haskell Neural Network library [1] is being rewritten from scratch. We (Thomas Bereknyi and I) are discussing many core data structure alternatives, with some suggestions from Edward Kmett. There may even be some room for a rewrite or update of fgl, possibly with an alternative conception, to fit well HNN. I am definitely not sure if this is worth a GSoC and if the community would benefit that much from such a work, but it's there.

I don't know whether this is a good idea for a GSoC project, but I would
certainly welcome such a library. I am using Haskell a bit for statistical
NLP: in my experience currently Haskell is excellent for the components
which deal with data preprocessing and feature extraction, but when it comes
to implementing the core training algorithms and running them on large data
sets, it's easy to get very poor performance and/or unexpected stack
overflows. So if a library could provide some well-tuned and tested building
blocks for implementing the performance critical parts of machine learning
algorithms, it would improve the coding experience in a major way.

Best,
