Rust ML WG Meeting 00022

Meeting Info

Date: 20210331

Start time: 1400ET

Updates on linfa
- Several PRs have been merged, a few more are getting underway
ndarray 0.15 has been released
- Larger update than from 0.13->0.14
- linfa currently using 0.13, ongoing PR for updating to 0.14
  - Pros/cons of trying to jump directly to 0.15 before the next major linfa release?
Rust-ML book is seeing some progress, but still a little slow
- Most of DBSCAN content, including comparison with KMeans is in draft PR, just needs some polishing
Manuel:
- Looking for an example (gradient generation) for my final thesis.
- Enzyme: Issues getting tests running
- Fixing convolution (once again) with chris?

linfa
- Partial least square algorithm added
- An algorithm found on /r/rust wrapped in t-SNE algorithm
- Updates for KMeans with different initialization techniques (interesting stuff regarding thread-local data storage), for KMeans++ and KMeans parallel
Manuel and Chris are going to try to finish backwards convolution pass this weekend
Manuel is moving forward with Enzyme for Rust for his bachelor's thesis
Blocking issue with sprs for adding 0.14 to linfa
- Remi thinks it makes sense to have at least one version of linfa with ndarray 0.14 to minimize possible dependency conflicts
- Ivano needs 0.14 for scaling as well
Ivano is continuting work on pre-processing
- Is working on figuring out a better way to do benchmarks
Starting linfa bindings to Python?
- Remi is interested
- Some Rust language constructs don't map 1-to-1, so that would be something to consider
- Lorenz happy to accept pull requests, but probably won't be actively working on it
- Remi might give it a shot once the 0.14 PR gets merged
- Mentioned the Luca wrote an intial Python binding for the first KMeans algorithm

Chris to reach out to book CI PR author, take over if not interestd in continuing
