# Rust ML WG Meeting 00023

## Meeting Info

Date: 20210414

Start time: 1400ET

Zoom: https://ucsb.zoom.us/j/6601852842

## Agenda

- DBSCAN chapter has been added to rust-ml book
- Starting work on ICA next

- Lorenz and Manuel added oxide-enzyme to the rust-ml Github repository. Highly WIP, but shows how to generate gradients with Enzyme.
- no type-tree generation for now, but got simple `f(x) = (x^2+1) + 2x` working (with nested functions)
- provide starting point for Manuel's thesis
- Give a small showcase?

- Linfa
- incremental KMeans implemented (@YuhanLiin)
- ~~almost ready for merging~~ merged: `linfa-preprocessing` by Ivano (@Sauro98)
- Platt scaling and multi class composing model needs review
- bump `linfa = 0.4`?

## Participants

- Chris
- Manuel
- Ricky
- ivano
- William
- yuhan
- Lorenz

## Minutes

- Meta
- Been a few weeks
- woo good number of people for this meeting!

- DBSCAN chapter has been added to rust-ml book
- :tada:
- independent component analysis next
- should go quicker

- Lorenz and Manuel added oxide-enzyme to the rust-ml group
- tried to integrate enzyme into Rust ecosystem
- basic prototype with type signature function for a heard start for manuel's thesis
- meets with supervisor tomorrow to announce thesis :clap:
- Screen sharing
- and poking through the code
- any pre or post processing optimization?
- no not yet
- you want all of the pre-optimizations on
- except vectorization and unrolling
- might want to enable post-processing optimizations on

- Linfa
- yuhan implemented an incremental k-means
- ivano merged `linfa-preprocessing` :tada:
- lorenz implmented platt scaling and multi-class composing model
- needs review though
- some examples are bad and could use some help digging into where it fails
- probably publish next linfa once platt scaling is merged
- blocked on the ndarray version with sparse matrix library in the trait system

- chrism writing licnensing artice for _The Gradient_
- machine learning, ethics, and open source licensing
- teneatively accepted for publication (parts 1 & 2)
- released over the next 2 or 3 weeks :tada:
- bio should say rust-ml WG :D so hopefully some exposure there!

- question on how does the new testing benchmarks for multi-thread/processing applications
- not totally sure about this with cache misses etc, but should always take results with a grain-of-salt

## Action Items

- chrism review the platt scaling MR
- https://github.com/rust-ml/linfa/pull/112
-
