R and Python, the “dynamic duo” of data science, are both free, open-source programming languages. That means that there’s no “vendor” in the sense that, say, Microsoft owns Excel. This can make getting started with these programs a little trickier: there are several ways to install them, often multi-step, ...

The BH package provides a sizeable portion of the Boost C++ libraries as a set of template headers for use by R. It is quite popular, and frequently used together with Rcpp. The BH CRAN page shows e.g. that it is used by rstan, dplyr as well as a ...

In continuation to my earlier R to Python tips, in order to deal with both Python and R simultaneously for client requests; this time with respect to plots where both schools as of now by large distinct in their plotting styles; Plotline a new python p...

Introduction Classification Data partition Train the model Prediction and confusion matrix Fine tuning the model Comparison between knn and svm model Regression Introduction In this paper we will explore the k nearest neighbors model using two data sets, the first is Tiatanic data to which we will fit this model ...

A task common to many machine learning workflows is to compare the performance of several models with respect to some metric such as accuracy or area under the ROC curve. Standard practice is to try out several different algorithms on a training data set and see which works better. Unfortunately, ...

In this post, we will go through the steps you need to follow if you would like to add a Jekyll / Github Pages blog to R-Bloggers. I recently went through this process and had to search through a lot of information in order to figure out how to do it. ...

H2O engineers continually innovate and implement latest techniques by following and adopting latest research, working on cutting edge use cases, and participating and winning machine learning competitions like Kaggle. But thanks to explosion of AI research and applications even most advanced automated machine learning platforms like H2O.ai ...

TL;DR mlr was refactored into mlr3. caret was refactored into tidymodels. What are the main differences in terms of software design, and tweaking it for your own needs. R6 vs S3. Which one is less fraigle? Motivation My previous post from mi...
