## nnetsauce’s new version

A new version of nnetsauce, v0.12.0, is available on PyPI and for conda. It’s been mostly tested on Linux and macOS platforms. For **Windows users**: you can use the Windows Subsystem for Linux in case it doesn’t work directly on your computer.

**As a reminder**, nnetsauce does Statistical/Machine Learning (regression, classification, and time series forecasting for now) using randomized and quasi-randomized *neural* networks layers. More precisely, every model in nnetsauce is based on components g(XW + b), where:

- X is a matrix containing explanatory variables and optional clustering information. Clustering the inputs helps in taking into account data’s heterogeneity before model fitting.
- W creates new, additional explanatory variables from X. W can be drawn from various random and quasi-random sequences.
- b is an optional bias parameter.
- g is an activation function such as ReLU or the hyperbolic tangent, that makes the combination of explanatory variables – through W – nonlinear.

**Examples** of use of nnetsauce are available on GitHub, here (including R Markdown examples) and here.

**v0.12.0 is an important release**, because it’s totally written in Python (using numpy, scipy, jax, and scikit-learn), and doesn’t use *C++* nor *Cython* anymore. Because of this, nnetsauce is faster to install, and easier to maintain.

## About nnetsauce for R

The R version is discontinued. Well, ‘discontinued’ until I finally wrap
my head around it… If you’re interested in solving this issue, and therefore, using nnetsauce for R,
everything happens in this R script.
You can submit a pull request (and **star the repo** ;) )!
