# Rust ML WG Meeting 00007

## Meeting Info

Date: 20200728

Start time: 1600 ET

https://ucsb.zoom.us/j/96478383368

Meeting ID: 964 7838 3368

## Agenda
- Progress on Linfa is continuing
- improve CI with testing (seems to be broken) and code formatting check
- attract more potential contributors
- write a Rust ML book, showcasing some existing algorithms
- how should `features` look like in linfa?
- chrism has started working on a library for parsing the CIFAR-10 binary files and returning an Array4<u8> data and Array2<u8> labels
- Not for general release yet, but could be useful
- https://github.com/quietlychris/cifar-10
- adding CIFAR-10 examples in `linfa`
-

## Participants
- chris m
- Lorenz
- Jed B.
- Patrick B.
- Paul K.
- Tiberio F.

## Minutes
- Discussed use of CIFAR-10 dataset for CNNs
- chris m's library has made progress, still needs to push commits
- linfa has accepted ~4 pull requests in the last couple weeks
- decision trees, logistic/linear regressions, common evaluation metrics
- Also need to evaluate the structure of linfa
- Automated testing
- Code formatting
- Adding machine learning showcase book
- Thinking about using features/feature gates for sub-crates?
- Machine learning showcase?
- No additional open pull requests

- Linfa to-dos
- Removing top-level example of K-means, or adding sub-crate examples to top-level
- make documentation reflect this

- Consider reorganizing linfa, such that sub-crates are in different repositories, etc.

- Considering making the machine learning showcase Book as a new repository to the rust-ml GH repo
- https://bytesnake.github.io/mdbook_example/ (see https://raw.githubusercontent.com/bytesnake/bytesnake.github.io/full/rendered/mdbook_example/example.md for source)

- Discussed existing autodifferentiation libraries
- GATs are needed; in the language pipeline, but not in stable at the moment
- autograd, autograph

- Tiberio discussed his webgpu library
- Currently supports matrix multiplication, reshaping, broadcasting
- Still under development, working on it in his free time
- Synchronous and async interfaces available
- He's writing a lot of tests, making sure of everything's correctness, then will transition to focusing on speed

## Actions

- Begin working on roadmap to Linfa 0.2 release (see suggestions above)
- Open issue on GitHub for ongoing conversation
- Restart CI pipeline, etc. --this needs to be updated, since repostory has changed ownership from Luca to the rust-ml org
