This post is mainly (but not only) a test, because I had a broken xml feed for my R posts, and I wanted to see if it was fixed.

It’s about my last R posts from june and july, which are:

• Using scikit-learn models in R easily with the tisthemachinelearner R package
• How conformalization helps weak models
• Fast Conformal Prediction for Some Machine Learning Models (jackknife+ and no refitting)

Using scikit-learn models in R easily with the tisthemachinelearner R package

This post is about the tisthemachinelearner R package, that allows to use scikit-learn models in R. It is a wrapper around the tisthemachinelearner Python package. Prediction intervals can be computed using either split conformal prediction, surrogate methods or the bootstrap.

How conformalization helps weak models

In this post, we compare split conformal prediction across several predictive models, using R package mlS3.

Fast Conformal Prediction for Some Machine Learning Models (jackknife+ and no refitting)

It’s surprisingly fast to obtain conformal jackknife+ prediction intervals for Machine Learning models of the form \(\hat{y} = Sy\) (including Ordinary Least Squares, Ridge Regression, Random Vector Functional Link Networks, Kernel Ridge Regression, smoothing splines, and local polynomial regression). No refitting involved, just Linear Algebra. Read https://www.researchgate.net/publication/408161842_Fast_Conformal_Prediction_for_Some_Machine_Learning_Models_via_Closed-Form_Jackknife.
